The 42 V ceiling covers 24 V industrial buses with margin for transients, and the 4.5 V minimum lets it start from a 5 V rail without a separate bias supply. Switching at 200 kHz, the regulator keeps the magnetics small enough for space-constrained designs while staying below the AM broadcast band where conducted emissions are harder to filter. ## Temperature grade and package for the board designer The output is adjustable and isolation-capable, meaning the regulator can drive a transformer primary to create a galvanically isolated secondary rail — useful when the load side must float relative to the input ground.","metaTitle":"MAX17681ATB+T Analog Devices Step-Down Buck Regulator, 42V","metaDescription":"MAX17681ATB+T active-production step-down buck regulator from Analog Devices. 42V input, 200kHz switching, adjustable output, -40 to 125°C.
