RT8243A Main Power Supply Controller

RT8243A Description

® RT8243A/B/C High Efficiency, Main Power Supply Controller for Notebook Computers General .
The RT8243A/B/C is a dual step down, Switch Mode Power Supply (SMPS) controller which generates logic supply voltages for battery powered systems.

RT8243A 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

RT8243A Applications

* an ultrasonic mode is
