RT8205L/M
High Efficiency, Main Power Supply Controller for Notebook Computer
General Description
The RT8205L/M 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.
An optional external charge pump can be monitored through SECFB (RT8205M).
The RT8205L/M includes on-board power up sequencing, a power good output, internal soft-start, and internal soft-discharge output that ...
