APPLICATION INFORMATION
The TPS75003 is an integrated power management IC designed specifically to power DSPs and FPGAs such as
the Xilinx Spartan-3, Spartan-3E and Spartan-3L. Two non-synchronous buck controllers can be configured to
supply up to 3 A for both CORE and I/O rails. A low dropout linear regulator powers auxiliary rails up to 300 mA.
All channels have independent enable and soft-start, allowing control of inrush current and output voltage ramp
time as required by the application.
Figure 2 shows a typical application circuit for powering the Xilinx Spartan-3 FPGA. Table 1 through Table 4
show component values that have been tested for use with 2-A and 3-A load currents. Other similar external
components can be substituted as desired; however, in all cases the circuits that are used should be tested for
compliance to application requirements.
