Additional preview pages of the RT6585A datasheet.

The RT6585A/B is a dual-channel step-down, controller generating supply voltages for batterypowered systems.

It includes two Pulse-Width Modulation (PWM) controllers adjustable from 2V to 5.5V, and two fixed 5V/3.3V linear regulators.

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 RT6585A/B automatically switches to the diode-emulation mode in light load.
