Product details

What this buck does — 3 V to 60 V in, 1.2 A out, synchronous

The Analog Devices LT8619EMSE#PBF is a synchronous step-down (buck) regulator that takes a 3 V to 60 V input and delivers an adjustable output down to 0.8 V at up to 1.2 A. The synchronous rectifier means you skip the external catch diode — the internal low-side switch handles it, which keeps the BOM short and the efficiency curve flatter across the load range. Switching frequency is programmable from 300 kHz to 2.2 MHz, letting you trade inductor size against ripple.

Frequently asked questions

What is the output current capability of LT8619EMSE#PBF?

The LT8619EMSE#PBF delivers up to 1.2 A continuous output current. For higher current needs, consider the LT8611EUDD#PBF at 2.5 A or the LT8620IMSE#PBF at 2.0 A.

Is LT8619EMSE#PBF synchronous rectification?

Yes, it uses synchronous rectification, which eliminates the need for an external Schottky catch diode and improves efficiency at moderate loads.

Are there alternatives to LT8619EMSE#PBF?

Within the same synchronous buck family, the LT8611EUDD#PBF offers 2.5 A output and the LT8620IMSE#PBF offers 2.0 A output, both with similar input voltage ranges and synchronous rectification. The LT8631HFE#PBF is a 1.0 A variant with a wider temperature range.
