TPS75003RHLR

The TPS75003RHLR 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 300mA LDO is integrated to provide an auxiliary rail such as VCCAUX on the Xilinx Spartan-3 FPGA. All three supply voltages are offered in user-programmable options for maximum flexibility.

• Two 95% efficient, 3A buck controllers and one 300mA LDO
• Adjustable (1.2 to 6.5V for bucks, 1.0 to 6.5V for LDO) output voltages on all channels
• Independent soft-start for each supply
• Independent enable for each supply for flexible sequencing
• LDO stable with 2.2µF ceramic output cap
