SGLS311A –DECEMBER 2006–REVISED MARCH 2011

Triple-Supply Power Management IC for Powering FPGAs and DSPs

Check for Samples: TPS75003-EP

FEATURES

APPLICATIONS

•

FPGA/DSP/ASIC Supplies

Set-Top Boxes

DSL Modems

Plasma TV Display Panels

•

Two 95% Efficient, 3-A Buck Controllers and

One 300-mA LDO

•

Tested and Endorsed by Xilinx for Powering

the Spartan™-3, Spartan-3E, and Spartan-3L

FPGAs

DESCRIPTION

•

Adjustable (1.2 V to 6.5 V for Bucks, 1 V to 6.5

V for LDO) Output Voltages on All Channels

The TPS75003 is a complete power management

solution for FPGA, DSP and other multi-supply

applications. The device has been tested with and

meets all of the Xilinx Spartan-3, Spartan-3E, and

Spartan-3L start-up profile requirements, including

monotonic voltage ramp and minimum voltage rail

rise time. Independent Enables for each output allow

sequencing to minimize demand on the power supply

at start-up. Soft-start on each supply limits inrush

current during start-up. Two integrated buck

controllers allow efficient, cost-effective voltage

conversion for both low and high current supplies

such as core and I/O. A 300-mA LDO is integrated to

provide an auxiliary rail such as V_CCAUXon the Xilinx

Spartan-3 FPGA. All three supply voltages are

offered in user-programmable options for maximum

flexibility.

•

Input Voltage Range: 2.2 V to 6.5 V

Independent Soft-Start for Each Supply

Independent Enable for Each Supply for

Flexible Sequencing

•

LDO Stable with 2.2-μF Ceramic Output

Capicitor

Small, Low-Profile 4,5 mm x 3,5 mm x 0,9 mm

QFN Package

SUPPORTS DEFENSE, AEROSPACE,

AND MEDICAL APPLICATIONS

•

Controlled Baseline

One Assembly/Test Site

One Fabrication Site

The TPS75003 is fully specified from –55°C to

+125°C and is offered in a QFN package, yielding a

highly compact total solution size with high power

dissipation capability.

Available in Military (–55°C/125°C)
