Product details

60V input, 1.5A switch — what this buck covers

The LT1956EFE#TRPBF is a step-down (buck) switching regulator from Analog Devices that accepts an input from 5.5V to 60V and delivers an adjustable output from 1.219V up to 54V via its internal 1.5A switch.

It is ROHS3 compliant.

Package and thermal: the exposed-pad detail

The 16-TSSOP with exposed pad (16-TSSOP-EP) is the key assembly detail. 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.

Frequently asked questions

Does LT1956EFE#TRPBF require an external diode?

Yes. 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. The diode rating should match the 1.5A switch current and the 60V input ceiling.

What is the difference between LT1956EFE#TRPBF and LT1956EFE (non-tape)?

The only difference is the packaging and shipping format. 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. The silicon, the 16-TSSOP-EP package, and all electrical ratings are identical.
