The 500kHz fixed switching frequency keeps the external inductor and capacitor small, which matters when board space is tight in industrial or automotive auxiliary supplies. It is a non-synchronous design — you supply the catch diode — and the 16-TSSOP package with exposed pad needs a thermal via stitch to the ground plane to handle the dissipation at full load. ## Active lifecycle — no LTB clock ticking This part carries an Active product status, so there is no last-time-buy window to track. It is ROHS3 compliant. For a BOM line that needs a wide-input-range buck in production, this is a clean qualification — no end-of-life risk on the horizon. ## Package and thermal: the exposed-pad detail The 16-TSSOP with exposed pad (16-TSSOP-EP) is the key assembly detail. The pad must be soldered to a copper plane on the PCB — without that thermal path the junction temperature climbs fast above 400 mA continuous output. The part is surface-mount only, and the tape-and-reel suffix (#TRPBF) means it ships on a 13-inch reel; cut-tape quantities are also available for prototyping.","metaTitle":"LT1956EFE#TRPBF 60V Step-Down Regulator, 1.5A, 500kHz","metaDescription":"LT1956EFE#TRPBF is an active 60V input, 1.5A buck regulator from Analog Devices.

This is a non-synchronous buck — there is no internal synchronous rectifier. You must add an external Schottky catch diode between the switch node and ground.

LT1956EFE#TRPBF is supplied on Tape & Reel (TR) and also available as Cut Tape (CT). The non-tape suffix variant typically ships in tubes or trays.
