Triple-Supply Power Management IC
for Powering FPGAs and DSPs
Checkfor Samples: TPS75003
1FEATURES DESCRIPTION
23• Two 95% Efficient, 3A Buck Controllers and The TPS75003isa complete power management
One 300mA LDO solution for FPGA, DSP and other multi-supply
applications. The device has been tested with and
• Tested and Endorsedby Xilinx for Poweringmeets allof the Xilinx Spartan-3, Spartan-3E and
the Spartan™-3, Spartan-3E and Spartan-3L Spartan-3L start-up profile requirements, including
FPGAs monotonic voltage ramp and minimum voltage rail
• Adjustable (1.2Vto 6.5V for Bucks, 1.0Vto rise time. Independent Enables for each output allow
6.5V for LDO) Output Voltages on All Channels sequencingto minimize demandon the power supply start-up. Soft-start on each supply limits inrush
• Input Voltage Range: 2.2Vto 6.5Vcurrent during start-up. Two integrated buck
• Independent Soft-Start for Each Supply controllers allow efficient, cost-effective voltage
• Independent Enable for Each Supply for conversion for both low and high current supplies
Flexible Sequencing suchas core and I/O.A 300mA LDOis integratedto
provide an auxiliary rail suchas VCCAUX on the Xilinx
• LDO Stable with 2.2mF Ceramic Output CapSpartan-3 FPGA. All three supply voltages are
• Small, Low-Profile 4.5mmx 3.5mmx 0.9mm offeredin user-programmable options for maximum
QFN Package flexibility.
