DESCRIPTION
23
• Two 95% Efficient, 3A Buck Controllers and
The TPS75003 is a complete power management
One 300mA LDO
solution for FPGA, DSP and other multi-supply
applications. The device has been tested with and
• Tested and Endorsed by Xilinx for Powering
meets all of 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 (1.2V to 6.5V for Bucks, 1.0V to
rise time. Independent Enables for each output allow
6.5V for LDO) Output Voltages on All Channels
sequencing to minimize demand on the power supply
at start-up. Soft-start on each supply limits inrush
• Input Voltage Range: 2.2V to 6.5V
current 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
such as core and I/O. A 300mA LDO is integrated to
provide an auxiliary rail such as V
