GENERAL DESCRIPTION
The XC9119D01A series is 1MHz, PWM controlled step-up DC/DC converter, designed to allow the use of ceramic capacitors. With a built-in 2.0 switching transistor, the XC9119D01A series can easily provide a step-up operation by using only a coil, a diode, a capacitor, and a resistor, connected externally. Since output voltage up to 19.5V (Maximum Lx operating voltage: 20V) can be derived with reference voltage supply of 1.0V (2.0%) and external components, the series can easily supply high voltage for various general-purpose power supplies, LCD panels and organic EL displays. With a high switching frequency of 1.0MHz, a low profile and small board area solution can be achieved using a chip coil and an ultra small ceramic output capacitor. With the current limit function (400mA (TYP.): VDD=3.6V), a peak current, which flows through built-in driver transistors can be limited. Soft-start time can be adjusted by external resistors and capacitors. The stand-by function enables the output to be turned off (CE 'L'), that is, the supply current will be less than 1.0A.

OPERATIONAL EXPLANATION
The XC9119D10A series consists of a reference voltage source, ramp wave circuit, error amplifier, PWM comparator, phase compensation circuit, driver transistor, current limiter circuit and others. The series ICs compare, using the error amplifier, the voltage of the internal reference voltage source with the feedback voltage from the FB pin. Phase compensation is performed on the resulting error amplifier output, to input a signal to the PWM comparator to determine the turn-on time during switching. The PWM comparator compares, in terms of voltage level, the signal from the error amplifier with the ramp wave from the ramp wave circuit, and delivers the resulting output to the buffer drive circuit to cause the Lx pin to output a switching duty cycle. This process is continuously performed to ensure stable output voltage. The current feedback circuit detects the N-channel MOS driver transistor's current for each switching operation, and modulates the error amplifier output signal to provide multiple feedback signals. This enables a stable feedback loop even when a low ESR capacitor, such as a ceramic capacitor, is used, ensuring stable output voltage. The reference voltage source provides the reference voltage to ensure stable output voltage of the IC. The ramp wave circuit determines switching frequency. The 1MHz (TYP.) of frequency is fixed internally. Clock pulses generated in this circuit are used to produce ramp waveforms needed for PWM operation. The error amplifier is designed to monitor output voltage. The amplifier compares the reference voltage with the FB pin voltage. When a voltage lower than the reference voltage is fed back, the output voltage of the error amplifier increases. Gain and frequency characteristics of the error amplifier output are fixed internally as an optimize signal. The current limit circuit of the XC9119D10A series monitors the current flowing through the N-channel MOS driver transistor connected to the Lx pin, and features a combination of the constant-current type current limit mode and the duty cycle limit of the next pulse. When the driver current is greater than a specific level, the constant-current type current limit function operates to turn off the pulses from the Lx pin at any given timing. The IC controls the next pulse to be smaller than the first pulse.

The current will be off when the coil current reaches the value of the constant current limit.
2
Limit some duty pulses after the limit.
The operation of the XC9119D10A series will enter into the shut down mode when a low level signal is input to the CE pin. During the shut down mode, the supply current is 0A (TYP.), with high impedance at the Lx pin. The IC starts its operation with a high level signal to the CE pin. The input to the CE pin is a CMOS input and the sink current is 0A (TYP.). The hysteresis between the chip enable and the chip disable is 50mV (TYP.). Soft-start function operates when capacitors and resistors are connected to the CE/SS pin. With the Vref voltage limited by the CE/SS pin start-up voltage and applying the input to the error amps, the operation maintains a balance between the two inputs of the error amps. and controls the Lx pin's ON time so that it doesn't increase more than is necessary. Depending of current limit function, load current, step-up ratio, and external components, the IC takes about 500uS to 5mS to attain the setting voltage after applying the CE `H' voltage even though the RSS is 0 and a soft start capacitor CSS is not connected. (For a numerical constant, please refer to Note on Use.) For longer soft-start time, please connect RSS and CSS. Soft-start function operates while the CE pin voltage is between 0V to around 1.9V. Please be noted that if the CE/SS pin voltage does not start from 0V but is in intermediate potential when the power is turned on etc., soft start function may lose an effect and that will cause a high inrush current and ripple voltage.

OPERATIONAL EXPLANATION
Pin No. 4 can be used as in either chip enable (CE) pin or soft-start (SS) pin. The IC takes about 5mS at most to attain the setting voltage after starting operation (CE `H') even though the RSS is 0 and the CSS is not connected. Soft-start function is good for setting a longer time than the start-up time when the RSS is 0 and the CSS is not connected. Soft-start operates while the CE pin voltage increases from 0V to around 1.9V. The following equation is used with the values of Vcont voltage, the RSS and the CSS. T = CSS x RSS x In {(Vcont - 1.6) / Vcont} Start-up waveform when the RSS is 0 and the CSS is not connected

OPERATIONAL EXPLANATION (Continued)
Please connect the anode of an Schottky barrier diode and inductor to the Lx pin. The reference voltage is 1.0V (TYP.). Output voltage is approximated by the following equation according to the value for two resistors (RFB1 and RFB2). The sum of the two resistors should be 1M or less. VOUT = RFB1 / RFB2 + 1 Output voltage should be set as to fill VOUT<(Maximum value of VLx) - (VF of Schottky diode). Please adjust the CFB value of the speed-up capacitor for phase compensation so that fzfb=1/(2x CFB x RFB1) will be about 500Hz. According to the usage, adjusting the inductance value, the load capacity value, and so on to the most suitable operation. Typical example: VOUT (V) 3.3 5.0 7.0 10.0 15.0 18.0 RFB1 (k) 300 300 180 270 510 510 RFB2 (k) 130 75 30 30 36 30 CFB (pF) 1000 1000 1800 1200 510 510
Please connect an input by-pass capacitor (CIN).
Application Information
In case that the input voltage VIN and power source VDD in the step-up circuit are isolated, the circuit starts step-up operations with the input voltage less than 2.5V when voltage from 2.5V to 6.0V is applied to the power source. Please connect more than 1uF of CDD between the VDD pin and the VSS pin as close as possible. Ex.) When VDD=3.6V, VIN=1.8V, VOUT=5.0V (RFB1=300k, RFB2=75k, CFB=1000pF, CL=10uF), the IC can operate up to IOUT=40mA.

NOTES ON USE
1. Please do not exceed the value of stated absolute maximum ratings. 2. The DC/DC converter performance is greatly influenced by not only the ICs' characteristics, but also by those of the external components. Care must be taken when selecting the external components. 3. Make sure that the PCB GND traces are as thick as possible, as variations in ground potential caused by high ground currents at the time of switching may result in instability of the IC. 4. Please mount each external component as close to the IC as possible and use thick, short connecting traces to reduce the circuit impedance. 5. Please set up the output voltage value so that the Lx pin voltage does not exceed 20V.

1. The measurement method of Lx On resistance RSWON Using the circuit , Lx On resistance can be measured by adjusting Vpull voltage to set Lx voltage VLx x 0.4V when the driver transistor is ON. The oscilloscope is used for measuring the Lx voltage when the driver transistor is ON. RSWON = 0.4 / {(Vpull - 0.4) / 10} 2. The measurement method of current limit ILIM Using the circuit , current limit ILIM can be calculate by the equation including Vpull voltage when FB voltage is decreased while Vpull voltage is adjusted and Lx voltage VLx when the driver transistor is ON.
