XRP7704

Quad-Output Digital PWM Buck Controller

September 2009

REV 1.1.0

KEY FEATURES

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 over-voltage

protection.

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

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 6.5V to 20V.

High Integration: elimination of external circuits and

components required for compensation, parameter

adjustment and interface

Programmable DPWM frequency range (300 kHz to 1.5

MHz) enables efficiency and component size optimization

I²C bus interface is provided to program the IC as well as to

communicate with the host for fault reporting and handling,

power rail parameters monitoring, etc.

Complete power monitoring and reporting

Independently controlled start-up delay and ramp for each

regulator, including soft start with a pre-biased load

voltage

The device offers a complete solution for soft-start and soft-

stop. The start-up delay and ramp of each PWM regulator

can be independently controlled. The device can start up a

pre-biased PWM channel without causing large negative

inductor current.

Independently controlled soft-stop delay and ramp for

each regulator with a programmable stop voltage

Over-temperature protection (OTP) and Under Voltage

Lockout (UVLO); per-channel over-current protection

(OCP) and over-voltage protection (OVP)

APPLICATIONS

Computing: Servers, Storage Systems

Built-in LDO (configurable to 3.3V or 5V) with over-current

protection

Consumer: Set-top box (STB), Game Systems

Industrial: ATE, DC-DC converters, Video Processing

Plasma Display Panel (PDP)

Non-volatile memory for system configuration

Configuration development tools
