RT8230A Datasheet (RICHTEK) - Dual-Channel Synchronous DC/DC Step-Down Controller

RT8230A, Dual-Channel Synchronous DC/DC Step-Down Controller

The RT8230A/B/C/D/E is a dual-channel step-down, controller generating supply voltages for battery-powered systems.

It includes two Pulse-Width Modulation (PWM) controllers adjustable from 2V to 5.5V, and two fixed 5V/ 3.3V linear regulators.

Each linear regulator provides up to 100mA output current
