FREMONT, Calif., Oct. 22, 2012 /PRNewswire/ -- Exar Corporation (Nasdaq: EXAR)
a leading supplier of analog mixed-signal products and data management
solutions, today announced the delivery of the XRP7724, a quad output
programmable power management system, and PowerArchitect™ 5.0, Exar's
comprehensive development tool. The XRP7724, with PowerArchitect 5.0, offers
architects an easy to use solution for complex power requirements providing
dynamic optimization and customizable configuration through on-board memory.

The XRP7724 is unequaled in both standby current and power consumption
performance with multiple Pulse Frequency Modulation (PFM) modes for improved
light load efficiency. Additionally, the XRP7724 minimizes printed circuit
board (PCB) space with the smallest solution footprint while significantly
lowering external part count. The XRP7724 delivers a wide variety of features
and capabilities that distinguishes programmable power  from legacy analog

"This announcement advances Exar's leadership position in programmable power
system solutions," said James Lougheed, vice president of power management
products. "The part is really only limited by an architect's imagination, for
example this solution could enable energy monitoring, remote field
upgradability, or a dynamically optimized power system."

Product Details
The XRP7724 is Exar's next-generation programmable power management system.
The system offers a single input, quad output, step down switching regulator
controller with integrated gate drivers and dual LDO outputs. The product is
programmable through an I²C based SMBus compliant serial interface. The
system offers a wide input voltage range (4.75V to 25V), and output range
(0.6V to 5.5V) with switching conversion frequencies programmable from 106kHz
to 1.2MHz in digital Pulse Width Modulation (PWM) and PFM modes. The XRP7724
offers the industry's lowest power consumption performance in standby (450uA)
and PFM mode (4mA). An additional five GPIOs for system control complete the
solution which is delivered in a 7x7mm TQFN package.

PowerArchitect™ 5.0 is Exar's next-generation design tool to complement the
XRP7724 product. This new release is a highly advanced tool that has been
upgraded to support all the new hardware features of the XRP7724 including
conditional sequencing, broader fault management, and more extensive GPIO
configuration. The tool also includes improvements such as chip verify,
auto-wizard inductor and capacitor value selection, multiple device
communication and improved status and interrupt register management. The tool
possesses an updated and more user friendly environment to aide designers in
their increasingly complex power supply designs.

About Power^XR Technology
Exar's Programmable Power Management family is marketed under the Power^XR
brand. The Power^XR family of products combines programmable power conversion
control and monitoring technology with high performance analog circuitry in
the industry's leading portfolio of programmable power management system
solutions. Power^XR enables system architects to create innovative products
with advanced, intelligent, switching power supplies that significantly reduce
wasted power and improve overall time to market compared to legacy analog
power-supply regulators.

Exar's PowerArchitect development tools enable designers to intelligently
configure the power supply's voltage setting and current thresholds, fault
monitoring and response, soft start and active shutdown timing, channel
sequencing, phase shift management and loop response amongst other features.
Dynamic control and full system monitoring enable system architects and power
designers alike to develop custom, proprietary system power designs that add
value to their end applications.

Product Availability and Pricing
The XRP7724 is available now in volume quantities and comes standard in a RoHs
compliant, halogen free 44 pin TQFN package. 1,000-unit price for the XRP7724
with PowerArchitect 5.0 is $6.75 each. Customers are encouraged to download
PowerArchitect™ 5.0 and test the ease of use and extensibility of the design
tool (registration required).
