TM
SC600
POWER MANAGEMENT Description
The SC600 is a versatile charge pump designed for use in battery operated power supply applications. The wide input range is matched for Li-Ion battery applications. mAhxLifeTM LED Drivers feature a fractional charge pump implementation with efficiency comparable to a switching regulator without costly inductors. Only two tiny ceramic capacitors are required, and the inductorless implementation provides a reduced-EMI solution. Patented low noise mode switching circuitry and constant output current allow the use of extremely small input and output capacitors. The SC600 charge pump can be used for applications that require up to 120mA of output current with a 4.0V or 4.5V output. The 5.0V output version provides up to 60mA of output current. mAhXLifeTM LED drivers replace switched mode power supplies and provide comparable efficiency with less cost, area, noise, and complexity.

POWER MANAGEMENT Applications Information
Regulated Fractional Charge Pump Operation A fractional charge pump is a voltage converter which implements switched capacitor techniques to produce an output voltage that is one of several multiples of the input voltage. Regulated fractional charge pumps (also called charge pump regulators) use a linear regulator with various charge pump configurations to deliver a regulated output over a wide input voltage range. Regulated fractional charge pumps have improved efficiency over ordinary linear regulator and charge pump circuit combinations. The improved efficiency is achieved by implementing multiple charge pump configurations on one integrated circuit. The correct charge pump configuration is automatically selected to meet the regulation requirements at the best possible efficiency. The SC600 has three charge pump configurations (modes), which multiply the input voltage by 1x, 1.5x and 2x. The charge pump configurations are implemented with two switched or 'bucket' capacitors plus the input and output capacitor. The bucket capacitors are configured for 1x mode at start-up to source current to the output capacitor and bring the output up quickly. The charge pump will begin switching in 1.5x mode. During normal operation, starting with a fully charged Li-Ion cell, the battery voltage will begin at about 4.1V. As the battery discharges and the voltage decays, the SC600 will eventually transition to 2x mode when the battery voltage is approximately 3.50V. Hysteresis is provided to prevent mode toggling. The output is prevented from exceeding 6.0V. This feature allows the use of 6.3V ceramic capacitors. mAhXLiFETM Advantage The plot on page 1 shows the efficiency of the SC600A. An example of a 5.0V regulated charge pump doubler is plotted to demonstrate how effective the SC600's 1.5x mode is at improving efficiency when the input voltage is above 3.5V. Most of the Li-Ion battery life is above 3.5V where the SC600 achieves more than 20% higher efficiency compared to the 5.0V regulated charge pump doubler with only a 2x mode. Following the efficiency curve from left to right as the battery discharges, the SC600A 5.0V remains in 1.5x mode until 3.5V and then transitions to 2x mode. Component Versions There are four versions of the SC600. The component selection table on page 4 highlights the differences between the component types. The three basic differences between the component versions are in the output voltage, maximum output current capability, and the mode transition point. The mode transition point is the value of input voltage at which the component will transition between 1.5x and 2x modes. 5.0V, 4.5V, and 4.0V versions are available. The SC600A (5.0V) is most efficient for applications that use up to 60mA. The SC600B (4.5V) and SC600C (4.5V) have different maximum output currents and mode transition points. The lower mode transition point of the SC600C allows it to remain in 1.5x mode longer for greater power savings. The SC600B has higher output capability, up to 120mA, and S600C is rated for 60mA. The SC600D (4.0V) is for applications using up to 120mA. Start-Up Conditions Typical start-up time is less than 50s. Caution: The SC600 must be enabled while 650kHz or 262kHz is selected to prevent over-voltage during start-up. LED Bias and Backlighting Applications When using the SC600 for LED bias, note that the SC600C and SC600D require the same input power per unit of output current even though the SC600C is more efficient. Also, the SC600A will have the same input power as the SC600B though the SC600A is more efficient. The following plots of Input Power vs. Input Voltage highlight the differences in application of the four component versions. To achieve the lowest possible input power, it is desirable for the charge pump to remain in 1.5x mode until the input voltage is as low as possible. The transition points from 1.5x to 2x are identified in the plot where the input power steps upward as the input voltage moves lower.

POWER MANAGEMENT Applications Information (Cont.)
Brightness Control with PWM Input Brightness control using a PWM input can be achieved with the application circuit below. Note that by connecting CX8 to the PWM signal the switching frequency is changed as the PWM signal changes. The charge pump operates at 262kHz during the on-time when there is a demand for current, and then changes to 32kHz when there is no load current. This is done to save battery power by taking advantage of the lower 280A quiescent current at 32kHz. The ripple voltage seen at the output is reasonable for LED applications, but the output capacitance can be increased to reduce the ripple if required. The sum of the LED currents for this circuit is 55mA during the on-time.

POWER MANAGEMENT
Applications Information (Cont.)
Comparison with Other Regulation Methods In many instances, a charge pump regulator is the best choice for portable power applications. These regulators offer many advantages over switch mode regulators. A smaller bill of materials, less layout area, lower component height, less noise, no EMF, and less overall circuit cost are typical reasons to use this type of regulation. In some cases the efficiency of a charge pump regulator exceeds the efficiency of a switch mode regulator. Inductors are often the largest and most expensive discrete component in a design. Because there are no inductors used in the SC600, cost, noise, layout area, as well as the the EMF associated with the inductor, are eliminated. The SC600's fixed frequency harmonics are an advantage in portable communications equipment, such as cellular telephones. The SC600 has distinct frequencies of operation, so the harmonics are predictable. The harmonics are not fixed in a switch mode regulator. Table 1 -Frequency Selection Logic
Sw itching Frequency 32kHz 8kHz 262kHz 650kHz C X8 0 0 1 1 CD4 0 1 0 1
Ripple Performance Examples of the output ripple, charge pump frequency and capacitor size are listed in Table 2. Switch mode regulators have harmonics which vary due to the pulse width modulation used to regulate the output. Varying harmonics can make it difficult to ensure acceptable noise performance over the entire operating range. Many switch mode regulators have increased voltage ripple on the output during pulse skipping mode due to large periods of time when no current is supplied to the output. The SC600 supplies current to the output continuously, so the voltage ripple is less than a switch mode regulator, even with greatly reduced output capacitance. The SC600 delivers a continuous current to the output during 1x, 1.5x and 2x modes. Most of the battery life requires 1.5x mode. Frequency Selection CX8 and CD4 are frequency select inputs; input from a P or other device may be used to change the charge pump frequency at any time (as shown in Table 1). The optimal frequency will depend upon the capacitor values, the load current, and the acceptable amount of output ripple. Lower frequencies will be more efficient, while higher frequencies will support higher output currents with lower ripple.

Mode Transition Impedance The mode transition impedance Ro refers to the output resistance of the charge pump before a transition to a stronger mode occurs. Ro is dependent upon the fractional charge pump, switching frequency, bucket capacitor value, bucket capacitor ESR, and the internal switch resistances. Ro is proportional to,
1 fC
A lower value of Ro will improve efficiency, so low ESR ceramic capacitors are required. An X7R or X5R dielectric is recommended. Y5V dielectric can require 2 to 3 times the rated value of an X7R dielectric for the same performance over the operating temperature range. Efficiency Efficiency for the SC600 is defined as,
VO IO
Ro can be measured to verify a low transition impedance. Before measuring Ro, select the capacitors, set the operating frequency and a constant load current. Find the input voltage just before a weak to strong mode transition (i.e., 1.5x to 2x mode). Measure VIN, VOUT, and IOUT before the transition. Ro will be, Ro=

where: VO = output voltage IO = output currrent mode = 1.5x or 2x VIN = input voltage IQ = quiescent current (from Electrical Characteristics on page 2) The mode may be identified by measuring input current and output current and calculating as mode = IIN/IOUT. Alternately, the mode can be identified by identifying the voltage at the bucket capacitor, CF1 with an oscilloscope. Calculating Power Dissipation The power dissipated by the SC600 is calculated as, PD = PIN - POUT PD = VIN * (mode IO + IQ) - VO * IO Suggested Capacitors The following is a short list of some of the manufacturers and types of multi-layer ceramic capacitors that are suggested for the SC600.

Short-Circuit and Over-Temperature Protection The output current is limited to 600mA to protect against short-circuit conditions. Over-temperature protection is also provided. Design and Layout Considerations The layout example on page 15 uses the 1206 case size for the capacitors, so a smaller layout area is possible. The bucket capacitors and the SC600 are on the same side of the card. To minimize trace inductance, traces are short and wide with no vias to the bucket capacitors. The input and output caps are on the bottom side directly under the SC600 and vias are used to connect directly to copper shapes used for the input and output. The input and output capacitors and Pin 8 should be connected to ground very near the SC600.
