The RT6576C/D is a dual-channel step-down controller generating supply voltages for battery-powered systems.

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

Each linear regulator provides up to 100mA output current and 3.3V linear regulator provides 1% accuracy under 35mA.

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 RT6576C/D automatically switches to the diode-emulation mode in light load.
