XRP7704 - Quad-Output Digital PWM Buck Controller

Description

The XRP7704 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.
  • 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.
  • High Integration: elimination of external circuits and components required for compensation, pa.

XRP7704 Quad-Output Digital PWM Buck Controller June 2018 GENERAL DESCRIPTION The XRP7704 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. Independent Digital Pulse Width Modulator (DPWM) channels regulate output voltages and provide all required protection functions such as current limiting and overvoltage protection. Each output voltage can be programmed from 0.9V to 5.1V without the need of an external voltage divider. The wide range of the programmable DPWM switching frequency (from 300 KHz to 1.5 MHz) enables the user to optimize between efficiency and component size.
