Datasheet Summary
RT6585A/B
Dual-Channel Synchronous DC-DC Step-Down Controller with 5V/3.3V LDOs
1 General Description
The RT6585A/B is a dual-channel step-down, controller generating supply voltages for batterypowered 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 RT6585A/B provides a mode selection pin, SKIPSEL, to select Diode-Emulation Mode (DEM) or Audio Skipping Mode (ASM). Other Features include on-board power-up sequencing, a power-good output, internal soft-start, and soft-discharge output...
