General Description
The RT6575C/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. The RT6575C/D has an oscillator
output to drive the external charge pump application. Other
features 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
RT6575C/D automatically switches to the diode-emulation
mode in light load applications. To eliminate noise in audio
applications, an audio-skipping mode is included, which
maintains the switching frequency above 25kHz. The
RT6575C/D is available in the WQFN-20L 3x3 package.
