RT8249D Product details

Description

The RT8249D 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 efficiency, the RT8249D automatically switches to the diode-emulation mode in light load.
