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.

Features

● Constant On-time Control with 100ns Load Step Response

● Wide Input Voltage Range : 6V to 25V

● Dual Adjustable Outputs from 2V to 5.5V

● Fixed 3.3V and 5V LDO Output : 100mA

● 2V Reference Voltage

● Frequency Selectable via TONSEL Setting

● 4700ppm/°C RDS(ON) Current Sensing

● Programmable Current Limit Combined with Enable Control

● Selectable PWM, DEM, or Ultrasonic Mode

● Internal Soft-Start and Soft-Discharge

● High Efficiency up to 97

● 5mW Quiescent Power Dissipation

● Thermal Shutdown

● RoHS Compliant and Halogen Free

Applications

● Notebook and Sub-Notebook Computers

● 3-Cell and 4-Cell Li+ Battery-Powered Devices
