SBVS052A–OCTOBER 2004–REVISED DECEMBER 2004

Triple-Supply Power Management IC

for Powering FPGAs and DSPs

FEATURES

DESCRIPTION

•

Two Buck Controllers Providing up to 3A and

One 300mA LDO for Powering 3 Supplies

The TPS75003 is a complete power management

solution for FPGA, DSP and other multi-supply appli-

cations. The device has been tested with and meets

all of the Xilinx Spartan-3 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

Tested and Endorsed by Xilinx for Powering

the Spartan™-3 and Spartan-3L FPGAs

Adjustable (1.2V to 6.5V for Bucks, 0.9V to

6.5V for LDO) Output Voltages on All

Channels

•

Independent Soft-Start for Each Supply

Independent Enable for Each Supply

integrated

buck

controllers

allow

efficient,

cost-effective voltage conversion for both low and

high current supplies such as core and I/O. A 300mA

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.

LDO Stable with Small 2.2µF Ceramic Output

Cap

•

Input Voltage Range: 2.2V to 6.5V

Small, Low-Profile 4.5mm x 3.5mm x 0.9mm

QFN Package

The TPS75003 is fully specified from -40°C to +85°C

and is offered in a QFN package, yielding a highly

compact total solution size with high power dissi-

pation capability.
