60V input, 1A output — the Himalaya workhorse for wide-VIN rails
The MAX17502EATB+T is a step-down buck converter from Analog Devices' Himalaya series, delivering a fixed 3.3V output at 1A from a 4.5V to 60V input range. The 60V maximum input means it handles 48V telecom rails, 24V industrial buses, and 12V automotive systems without an external pre-regulator — the internal FET's breakdown margin covers transients up to the abs-max rating.
Switching at 600 kHz with synchronous rectification
The 600 kHz switching frequency lets the output inductor and capacitor shrink below what a 100 kHz part would need — a 10 µH inductor and 22 µF ceramic cap are typical for a 3.3V rail at 1A.
