® RT8230A/B/C/D/E Dual-Channel Synchronous DC/DC Step-Down Controller with 5V/3.3V LDOs General Description 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. The 5V linear regulator supplies power to the PWM drivers. The RT8230A/B/C/D/E includes on-board power-up sequencing, a power-good output, internal soft-start, and soft-discharge output that prevents negative voltage during shutdown. A constant current ripple PWM control scheme operates without sense resistors and provides 100ns response to load transient.
