Product details

3A buck with military temperature range

The TPS5430MDDAREPG4 is a SWIFT™ step-down buck regulator from Texas Instruments, delivering 3A continuous output from a 5.5V to 36V input rail.

Output voltage and external components

The part does not integrate synchronous rectification, so the freewheeling diode must be a Schottky rated for the full 3A output plus margin — a 40V/5A Schottky in the same PowerSOIC footprint is a common pairing. The 500kHz fixed switching frequency allows a 10µH to 22µH inductor for most 3A designs. The compensation network is internal, so the BOM stays to the basic buck loop: input cap, output cap, inductor, catch diode, and feedback divider.

The supplier device package is 8-SO PowerPad, which is the same mechanical outline.
