General Description

The XC9301/XC9302 series are step-up/down DC/DC converter controller ICs with fast, low ON resistance drivers built-in.

A ç 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 (ʶ2.5% accuracy) range and switching frequency is set at 180kHz or 300kHz.

Key Features
