RT8239B Features

* include on board power up sequencing, a power good output, internal softstart, and a soft discharge output that prevents negative voltage during shutdown. A constant on-time PWM control scheme operates without sense resistors and assures fast load transient response while maintaining nearly constant

RT8239B General Description

The RT8239A/B/C is a dual step down, Switch Mode Power Supply (SMPS) controller which generates logic supply voltages for battery powered systems. It includes two Pulse Width Modulation (PWM) controllers adjustable from 2V to 5.5V and also two fixed 5V/3.3V linear regulators. One of the controllers .
