RT8205M - Main Power Supply Controller

Download the RT8205M datasheet PDF. This datasheet also covers the RT8205L variant, as both devices belong to the same main power supply controller family and are provided as variant models within a single manufacturer datasheet.

Description

The RT8205L/M is a dual step-down, switch mode power supply controller generating logic-supply voltages in battery powered systems.

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 prevents negative voltage during shutdown. The constant on-time PWM control scheme operates without sense resistors and provides 100n.

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 prevents negative voltage during shutdown.
