The RT6575A/B 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 and 3.3V linear regulator provides 1% accuracy under 35mA. The RT6575A/B has an oscillator output to drive the external charge pump application. Other features include on-board power-up sequencing, a powergood output, internal soft-start, and soft-discharge output that prevents negative voltage during shutdown.
