RT6545A/B
Dual-Channel Synchronous DC/DC Step-Down Controller with 5V/3.
3V LDOs
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.
3V linear regulator provides 1% accuracy under 35mA.
The RT6545A/B has an oscillator output to driver 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 durin...
