Product details

3.4V to 60V input, 100 mA output — wide-range buck for harsh environments

The LT8618JDDB#TRMPBF is a step-down (buck) switching regulator from Analog Devices that accepts an input from 3.4V up to 60V and delivers a regulated adjustable output down to 0.778V at 100 mA. The wide input range covers 12V, 24V, and 48V industrial rails without a pre-regulator, and the 125°C junction rating suits under-hood or high-ambient enclosures.

Switching frequency trade-off and package footprint

At the low end, efficiency peaks and the inductor ripple current drops; at the high end, the inductor and output capacitor shrink, but switching losses rise.

Frequently asked questions

What package does LT8618JDDB#TRMPBF use?

It is supplied in a 10-lead WFDFN with exposed pad, 3x2 mm body (supplier device package 10-DFN). The pad must be soldered to the PCB ground plane for thermal management.

Is LT8618JDDB#TRMPBF RoHS compliant?

Yes, it is ROHS3 compliant.
