RT6575K - High Efficiency Single Synchronous DC-DC Step-Down Controller

Datasheet Summary

Description

RT6575K is a single-channel step-down controller generating supply voltage for battery-powered systems.

It includes a Pulse-Width Modulation (PWM) controller adjustable from 2V to 5.5V, and a fixed 5V linear regulator.

The linear regulator provides up to 100mA output current.

Features

include on-board powerup 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. For maximizing power efficiency, the RT6575K automatically switches to the diode-emulation mode in light load.
