QFN Package
DESCRIPTION
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
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
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 -40擄C to +85擄C
and is offered in a QFN package, yielding a highly
compact total solution size with high power dissi-
pation capability.
