RT8223M - Main Power Supply Controller

Download the RT8223M datasheet PDF. This datasheet also covers the RT8223L variant, as both devices belong to the same main power supply controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The RT8223L/M is a dual step-down, switch-mode power supply controller generating logic-supply voltages in battery-powered systems.

Key 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 RT8223L/M 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 without sense resistors and provide 100ns load transient response while maintaining nearly constant switching frequency. To elimin.

RT8223L/M High Efficiency, Main Power Supply Controller for Notebook Computer General Description The RT8223L/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. The RT8223L/M includes on-board power up sequencing, a power good output, internal soft-start, and soft-discharge output that prevents negative voltage during shutdown.
