XRP7740 - Quad-Output Digital PWM Buck Controller

Description

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.

The device provides a complete power management solution in one IC and is fully programmable via the included I2C serial interface.

Features

  • 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.
