The XC9101 series is a PWM controlled step-up DC/DC controller with multiple current and voltage feedback functions. Current sense, clock frequencies, and amp feedback gain can all be externally regulated. It allows for a stable power supply with output currents of up to 1.5A. The output voltage is fixed internally and can be selected in 0.1V increments within a range of 2.5V ~ 16.0V (±2.5%). For output voltages outside this range, the FB version with a 0.9V internal reference voltage is recommended. Using this version, the required output voltage can be set using 2 external resistors. The switching frequency can also be set externally within a range of 100 ~ 600 kHz, allowing for selection of a frequency suited to the specific application. The current sense function enables control of peak currents flowing through the driver transistor and coil. The soft-start time can be adjusted using an external resistor and capacitor. During shutdown (CE pin=L), the consumption current can be reduced to as little as 0.5μA (TYP.) or less.
