RT8249A/B/C
Dual-Channel Synchronous DC/DC Step-Down Controller with 5V/3.
3V LDOs
General Description
The RT8249A/B/C 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 RT8249A/B has an oscillator output to driver the external charge pump application.
The RT8249C provides a mode selection pin, SKIPSEL, to select Diode-Emulation Mode (DEM) or Audio Skipping Mode (ASM).
Other features include on-board p...
