RT8249A, Dual-Channel Synchronous DC/DC Step-Down Controller

® RT8249A/B/C Dual-Channel Synchronous DC/DC Step-Down Controller with 5V/3.3V LDOs General .
The RT8249A/B/C is a dual-channel step-down, controller generating supply voltages for battery-powered systems.

Features

* include on-board power-up sequencing, a power-good output, internal soft-start, and soft-discharge output that prevents negative voltage during shutdown. A constant current ripple PWM control scheme operates without sense resistors and provides 100ns response to load transient. For maximizing power
