The XRP7740 is a quad-output pulse-width modulated (PWM) step-down DC-DC controller with a built-in LDO for standby power and GPIOs.

Four switching buck (step-down) controllers each with internal FET drivers. Two controllers (2 & 4) support loads up to 15A; two controllers (1 & 3) support load up to 5A.
6.5V to 20V input voltage range.
no additional voltage rails required.
Output voltages programmable from 0.9V to 5.1V.
Up to 6 reconfigurable GPIO pins.
Fully programmable via I2C interface.
Independent Digital Pulse Width Modulator (DPWM) channels with five coefficient PID control.
