Three Channel Digital PWM Step Down Controller

December 2010

Rev. 1.1.1

GENERAL DESCRIPTION

APPLICATIONS

The XRP7713 is a three 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 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.

• Multi Channel Power Supplies

• Audio-Video Equipments

• Industrial & Telecom Equipments

• Processors & DSPs Based Equipments

FEATURES

• 3 Channel Step Down Controller

− Programmable Output Voltage 0.9V-5.1V

− Programmable 1.5MHz DPWM Frequency

− Integrated FET Drivers

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. Input voltage range is from 4.75V to

• 4.75V to 5.5V and 5.5V to 25V Input

Voltage Range

• Up to 5 Reconfigurable GPIO Pins

• Fully Programmable via I²C Interface

• Independent Digital Pulse Width

Modulator (DPWM) channels

25V.

An I²C bus interface is provided to

• Complete Monitoring and Reporting

• Complete Power Up/Down Sequencing

program the IC as well as to communicate

with the host for fault reporting and handling,

power rail parameters monitoring, etc.

• Full On Board Protection

OTP, UVLO, OCP and OVP

The device offers a complete solution including

independently programmable: soft-start, soft-

stop, start-up delay and ramp of each PWM

regulator.

• Built-in 3.3V/5V LDO

• PowerArchitect™ Design Software

• Green/Halogen Free 32-pin TQFN
