1 / 29 page TPS75003-EP www.ti.com SGLS311A – DECEMBER 2006 – REVISED MARCH 2011 Triple-Supply Power Management IC for Powering FPGAs and DSPs Check for Samples: TPS75003-EP 1 FEATURES APPLICATIONS • FPGA/DSP/ASIC Supplies 2 • Two 95% Efficient, 3-A Buck Controllers and • Set-Top Boxes One 300-mA LDO • DSL Modems • Tested and Endorsed by Xilinx for Powering • Plasma TV Display Panels 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 The TPS75003 is a complete power management V for LDO) Output Voltages on All Channels solution for FPGA, DSP and other multi-supply • Input Voltage Range: 2.2 V to 6.5 V applications. The device has been tested with and • Independent Soft-Start for Each Supply meets all of the Xilinx Spartan-3, Spartan-3E, and Spartan-3L start-up profile requirements, including • Independent Enable for Each Supply for monotonic voltage ramp and minimum voltage rail Flexible Sequencing rise time. Independent Enables for each output allow • LDO Stable with 2.2- μF Ceramic Output sequencing to minimize demand on the power supply Capicitor at start-up. Soft-start on each supply limits inrush • Small, Low-Profile 4,5 mm x 3,5 mm x 0,9 mm current during start-up. Two integrated buck QFN Package 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 SUPPORTS DEFENSE, AEROSPACE, provide an auxiliary rail such as VCCAUX on the Xilinx AND MEDICAL APPLICATIONS Spartan-3 FPGA. All three supply voltages are • Controlled Baseline offered in user-programmable options for maximum • One Assembly/Test Site flexibility. • One Fabrication Site The TPS75003 is fully specified from –55°C to • Available in Military ( –55°C/125°C) +125 °C and is offered in a QFN package, yielding a highly compact total solution size with high power Temperature Range(1) dissipation capability. • Extended Product Life Cycle • Extended Product-Change Notification • Product Traceability (1) Additional temperature ranges available - contact factory 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 Spartan is a trademark of Xilinx, Inc.
