SUPPORTS:
-
-
Spartan™-3
FEATURES:
-
-
High efficiency minimizes heat
-
-
Interchange SWIFT
T M
device to support 1.5 A to 3 A load currents
o
1.5A (TPS54110) and 3A (TPS54310) synchronous SWIFT devices are
pin-pin compatible
-
-
Use of the TPS54x10 adjustable devices allow
o
use of smallest inductor and/or specific type of output capacitor
o
flexibility to re-compensate as needed, depending on the
bypass/decoupling capacitors used with the FPGA
-
-
In-rush current (for charging decoupling caps and FPGA start-up) that places a
demand on the input power supply is minimized by the use of optional
demand on the input power supply is minimized by the use of optional
o
Integrated soft-start configured with an capacitor to provide 10 ms rise
time for V

-
High UVLO trip point and integrated soft-start of the SWIFT
T M
devices
eliminates the need for an external Supply Voltage Supervisor (SVS) to monitor
the input rail.
