XRP7708 Datasheet Quad Channel Digital Pwm Step Down Controller

Manufacturer: Exar (now MaxLinear)

Overview: .. X RP 7 7 0 8 Rev. 1.0.3 Quad Channel Digital PWM Step Down Controller February 2010.

General Description

The XRP7708 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 plete power management solution in one IC and is fully programmable via an I2C serial interface.

Independent Digital Pulse Width Modulator (DPWM) channels regulate output voltages and provide all required protection functions such as current limiting and over-voltage protection.

Key Features

  • 4 Channel Step Down Controller.
  • 2 x 5A Channels & 2 x 8A Channels.
  • Programmable Output Voltage 0.9V-5.1V.
  • Programmable 1.5MHz DPWM Frequency.
  • 6.5V-20V Single Input Voltage Range.
  • Up to 6 reconfigurable GPIO pins.
  • Fully programmable via I2C interface.
  • Independent Digital Pulse Width Modulator (DPWM) channels.
  • Complete power monitoring and reporting.
  • Full On Board Protection OTP, UVLO, OCP and OVP.
