Overview
® RT8249D Dual-Channel Synchronous DC/DC Step-Down Controller with 5V/3.
3V LDOs General Description The RT8249D 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 RT8249D 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 that pr...
