3.5A step-down with synchronous rectification
The LT8610AEMSE#PBF is a monolithic step-down buck regulator from Analog Devices, delivering up to 3.5 A continuous output from a 3.4 V to 42 V input rail. The internal synchronous rectifier eliminates the external catch diode, keeping the BOM count low on a single-layer power stage. The 200 kHz to 2.2 MHz switching frequency range lets you trade inductor size against efficiency — run at 2.2 MHz to shrink the magnetics into a 0805 footprint, or drop to 200 kHz for best light-load efficiency.
Industrial temperature grade and supply range
The 42 V input maximum handles 24 V industrial rails with margin for transients up to 40 V, and the 3.4 V minimum lets it start from a 3.6 V lithium cell near end-of-discharge.
ROHS3 compliant, so it passes into EU and California markets without exemption paperwork.
