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.
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 switching frequency. To eliminate noise in audio.
