Additional preview pages of the RT6545A datasheet.

The RT6545A/B is a dual-channel step-down, controller generating supply voltages for battery-powered systems.

include on-board power-up sequencing, a powergood 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 RT6545A/B automatically switches to the diode-emulation mode in light load.
