Overview

RT8223N High Efficiency, Main Power Supply Controller for Notebook Computer General Description The RT8223N is a dual step-down, switch-mode power supply controller generating logic-supply voltages in battery-powered systems.
It includes two Pulse Width Modulation (PWM) controllers adjustable from 2V to 5.
5V, and also features fixed 5V/3.
3V linear regulators.
Each linear regulator provides up to 100mA output current with automatic linear regulator bootstrapping to the PWM outputs.
The RT8223N includes on-board power up sequencing, a power good output, internal soft-start, and soft-discharge output that prevents negative voltage during shutdown.
The constant on-time PWM scheme can operate w...
