Introduction

AI Translation

The XC9301/XC9302 series are step-up/down DC/DC converter controller ICs with fast, low ON resistance drivers built-in. A versatile, large output current, step-up/down DC/DC converter can be realized using only 4 type of basic external components two transistors, one inductor, two diodes and capacitors. Output voltage is selectable in 0.1V increments within a 2.4V~6.0V (± 2.5% accuracy) range and switching frequency is set at 180kHz or 300kHz. The XC9302 series switches from PWM to PFM control during light loads and the series offers high efficiencies from light loads through to large output currents. Soft-start time is internally set to 10ms which offers protection against inrush currents when the power is turned on and also against voltage overshoot. During shutdown (CE pin = L), consumption current can be reduced to as little as 0.5μA or less.
