DESCRIPTION
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_CCAUX on the Xilinx
Spartan-3 FPGA. All three supply voltages are
offered in user-programmable options for maximum
flexibility.
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.
