AS1301
5V/50mA Low Noise Inductorless Boost Converter
D a ta S he e t
1 General Description
The AS1301 is a 50mA inductorless boost converter using a double H-bridge charge-pump topology with two external flying capacitors. The AS1301 runs on a 1MHz fixed frequency and is utilized with a low noise regulation scheme to allow usage together with sensitive RF circuitry from the same battery supply. Designed to reside in portable and space limited equipment the 1MHz charge pump converts a 2.7 to 5.25V input to regulated 5V output with 5% accuracy. The shutdown function reduces the supply current to <5A and disconnects the load from the output. The integrated soft-start circuitry prevents current spikes being drawn from the battery during start-up. The AS1301 is available in TDFN (3x3x0.8mm) 10-pin and WL-CSP 8-bumps packages.

Operating Principle
Functional Description
The AS1301 is a high efficiency and low noise switched capacitor DC/DC converter that is capable of boost operation. It is equipped with two built-in coupled H-bridge type switch configurations. Based on the value of the output voltage the system automatically initiates mode up-switching to achieve the highest possible efficiency. The regulation of the output voltage is achieved by a regulation loop, which modulates the on-resistance of the power transistors so that the amount of charge transferred from the input to the output at each clock cycle is controlled and is equal to the charge needed by the load.
Regulation Loop
The AS1301 operates at constant frequency at any load. For the regulation loop power transistors, a resistor divider, and an error amplifier is used to keep the output voltage within the allowed limits. The error amplifier, including loopfilter and compensation ramp, takes feedback and reference as inputs and generates the error voltage signal. The error voltage is then used as the gate voltage of the power transistor which modulates the on-resistance of the latter. The modulated transistor on-resistance controls the charge transferred from the input to the output and therefore the regulation of the output is realized. Based on adjusting of the amount of charge transferred, this regulation concept delivers the smallest voltage ripple possible. Figure 26. Functional Block Diagram

- Detailed Description
Switch Configuration
The AS1301 has nine built-in power switches in the shape of two coupled H-bridge topologies. The system features 1:2 and 2:3 operation mode as well as an 1:1 operation where the input is directly connected to the output. This feedthrough mode is suitable for input voltages higher than the output voltage. In 2:3 operation mode two flying capacitors are placed in series and each capacitor is charged to a half of the input voltage. In pumping phase the flying capacitors are place in parallel. The bottom-plate of the parallel flying capacitors CFLY1 and CFLY2 is then connected to the input voltage so that the voltage at the top-plate of the flying capacitors is boosted to a voltage equal to VBATT+ VBATT/2. By connecting the top-plate of the capacitors to the output, the output voltage in 2:3 mode can be up to one and a half of VBATT. If the top-plate voltage is higher than 5V, the regulation loop adapts the power transistor's on-resistance to drop some voltage. The 2:3 operation mode runs in single-phase operation only. Figure 27. 2:3 Single Phase Operating Mode
Charging Flying Capacitors VOUT SW1 SW2 VBATT CFLY1 CFLY2 SW3 SW4 SW4 VBATT SW2 CFLY1 CFLY2 SW3 SW1 Generating Output Voltage VOUT
In 1:2 operation mode just one of both flying capacitors is placed in series to the input voltage, and therefore charged to the input voltage. During pumping phase the input voltage is connected to the bottom of the charged flying capacitor CFLY. The voltage at the top-plate of the capacitor is now boosted to 2VBATT. By connecting the top-plate of the capacitor to the output, the output can be charged to double of VBATT. If the top-plate voltage is higher than 5V the regulation loop limits the charge transfer to the output. In collaboration with the second flying capacitor this mode features dual-phase operation.

- Detailed Description
Overload Protection
When the output voltage drops about 200mV below battery voltage due to very high load the AS1301 enters overload protection condition. In this condition the output is connected to the input via a current limiting connection. Once the overload is removed, the device enters soft start periode and ramps up to the nominal output voltage.
Undervoltage Lockout
The AS1301 is equipped with an undervoltage lockout functionality. If the battery voltage drops below 2.7V (typ) the device enters the undervoltage lockout condition. The device remains in this condition until the battery voltage is high enough to enter the soft start period. An internal hysteresis of 100mV will prevent ringing during startup. If the input voltage climbs back to 2.8V (typ) after such a condition the device will turn-on automatically again.
Shutdown Mode
The AS1301 enters low-power shutdown mode when EN is logic low. In shutdown the charge-pump action is halted, the output is completely disconnected from the input and VOUT will drop to 0V. During shutdown the output voltage can be forced higher then the input voltage, because the permanent monitoring of the input- and output voltage will prevent an erroneous current form the output back to the input during shutdown.
Thermal Shutdown
The AS1301 offers thermal shutdown, which prevents eventual damage due to an over-temperature condition. Thermal shutdown will be initiated if the junction temperature exceeds 145C. If the temperature drops below this value, the thermal shutdown will be released automatically and the device will resume operation.

9 Application Information
External Component Selection
The high internal oscillator frequency of 1MHz permits the use of small capacitors for both the flying capacitors and the output capacitors. For any given load value of the flying- and output capacitors as well as their ESR are affecting the output voltage performance. In general, the capacitor's ESR is inversely proportional to its physical size. Larger capacitances and higher voltage ratings tend to reduce ESR. The ESR is a function of the frequency too, so it must be rated at the devices operating frequency. Another factor affecting capacitor ESR is temperature. Note: Many capacitors have a huge capacity variation over temperature. This can be compensated by choosing a capacitor with a better thermal coefficient or by choosing a larger nominal value to ensure proper operation over temperature.
Input and Output Capacitor Selection
It is not critical which type of input bypass capacitor CBAT and output filter capacitor COUT is used, but it will still affect the performance of the charge-pump. Low ESR capacitors should be used to minimize VOUT ripple. Multi-layer ceramic capacitors are recommended since they have extremely low ESR and are available in small footprints.
Input Capacitor
An 1.2F/2.2F input bypass low ESR capacitor such as tantalum or ceramic is recommended to reduce noise and supply transients. During startup and mode change it supplies part of the peak input current drawn by the device. Table 4. Recommended Input Capacitor Part Number GRM21BR71A225KA01 C 2.2F TC Code Rated Voltage Dimensions (L/W/T) X7R 10V 2x1.2x1.35mm Manufacturer Murata www.murata.com
Output Capacitor
The output capacitor is charged to the VOUT voltage during pumping phase. The ESR of the output capacitor introduces steps in the output voltage waveform whenever the charge pump charges COUT. These steps contribute to the ripple voltage of VOUT. Therefore, ceramic or tantalum low ESR capacitors are recommended for COUT to minimize the output voltage ripple. Table 5. Recommended Output Capacitor Part Number GRM21BR71A225KA01 C 2.2F TC Code Rated Voltage Dimensions (L/W/T) X7R 10V 2x1.2x1.35mm Manufacturer Murata www.murata.com
Charge-Pump Capacitor Selection
To ensure the required output current and avoid high peak currents the values of the flying capacitors CFLY1 and CFLY2 are very critical. A 120nF capacitor is sufficient for most applications. Dependent on the operation mode the AS1301 alternately charges and discharges the CFLY1/2 . While the ESR of the output capacitor produces part of the output voltage ripple, the voltage drop caused by the ESR of the flying capacitors affects the maximum available output voltage. Therefore low ESR capacitors, e.g. tantalum or ceramic, are recommended for the flying capacitors as well. Table 6. Recommended Charge-Pump Capacitor Part Number GRM188R71E224KA88 C 220nF TC Code Rated Voltage X7R 25V Dimensions (L/W/T) 1.6x0.8x0.87mm Manufacturer Murata www.murata.com
