XRP7720

Quad Output Universal Customizable PMIC with PFM

January 2014

Rev. 1.0.0

GENERAL DESCRIPTION

FEATURES

 Pin Compatible to XRP7724

The XRP7720 is a quad output universal

customizable PMIC comprised of a quad

channel Digital Pulse Width Modulated (DPWM)

Step down (buck) controller and 5V LDO. A

wide 4.75V to 5.5V and 5.5V to 18V input

voltage dual range allows for single supply

operation from standard power rails. It is pin

compatible to the popular XRP7724 and

provides full flexibility during the development

phase while offering a cost effective option for

high volume production units.

 SMBus Compliant I²C Interface available

on XRP7720ILB-DEV Only

 Supported by PowerArchitect™ 5.1

 XRP7720ILB-DEV Only

 Quad Channel Step-down Controller

 Digital PWM 105kHz-1.23MHz Operation

 Individual Channel Frequency Selection

 Patented digital PFM with Ultrasonic Mode

 Integrated MOSFET Drivers

With integrated FET gate drivers, it can

operate from 105kHz to 1.23MHz with

 Programmable 5 coefficient PID control

 4.75V to 18V Input Voltage

independent

programmable

channel-to-channel

operating frequency, the

 4.75V-5.5 and 5.5V-18V Input Range

 0.6V to 5.5V Output voltage

XRP7720 reduces overall component count

and solution footprint while optimizing

conversion efficiencies.

A selectable digital

 3 x 15V Capable PSIOs + 2 x GPIOs

 Full Start/Stop Sequencing Support

Pulse Frequency Mode (DPFM) and low

operating current result in better than 80%

efficiency down to 10mA load provides support

for portable and Energy Star compliant

applications. Each XRP7720 output channel is

 Built-in Thermal, Over-Current, UVLO

and Output Over-Voltage Protections

 On Board 5V Standby LDO

 7x7mm TQFN44 Package

individually

programmable

down

minimum 0.6V with a resolution of 2.5mV, and

configurable for precise soft start and soft stop

sequencing, including delay and ramp control.

APPLICATIONS

During development, the XRP7720ILB-DEV is

configured using PowerArchitect^TM5.1 (PA 5.1)

through an I²C interface, allowing for short

development of the power system and short

time to market for the entire system. Once

development is completed and volume

production is ready to commence, Exar will

assign a unique part suffix and deliver a

customized XRP7720.

 Blade Servers

 Micro Servers

 Network Adapter Cards

 Switches/Routers

 Video Surveillance Systems

Built-in independent output over voltage, over

temperature, over-current and under voltage

lockout protections ensure safe operation

under abnormal operating conditions.

The XRP7720 is offered in a RoHS compliant,

“green”/halogen free 44-pin TQFN package.
