RT6575 - Dual-Channel Synchronous DC-DC Step-Down Controller

General Description

The RT6575 family is a dual-channel step-down controller designed to generate 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.

Key Features

  • an oscillator output to drive the external charge pump.

RT6575 Dual-Channel Synchronous DC-DC Step-Down Controller with 5V/3.3V LDOs 1 General Description The RT6575 family is a dual-channel step-down controller designed to generate 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 RT6575 features an oscillator output to drive the external charge pump application. Other features include on-board power-up sequencing, a power-good output, internal soft-start, and softdischarge output that prevents negative voltage during shutdown.
