Dual-Channel Synchronous DC/DC Step-Down Controller

Richtek

RT6545B Features

* include on-board power-up sequencing, a powergood 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 e

RT6545B General Description

The RT6545A/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..
