60 V input, 1 A output — Himalaya step-down for industrial rails
The MAX17502FATB+T is a Himalaya family synchronous buck regulator from Analog Devices (formerly Maxim Integrated) that accepts a 4.5 V to 60 V input and delivers a fixed 5 V output at up to 1 A. The 600 kHz switching frequency keeps the inductor small while staying clear of the AM broadcast band. Internal synchronous rectification eliminates the external catch diode and improves efficiency across the load range, especially at light loads — relevant for always-on industrial or telecom supplies where standby power matters. The 10-TDFN (3x2 mm) package with exposed pad pulls heat into the PCB copper; layout needs a solid thermal via pattern under the pad for full current capability at elevated ambient temperatures.
Synchronous rectifier and thermal range — fit for industrial and automotive environments
Junction temperature range is -40°C to +125°C. Synchronous rectifier maintains efficiency at light loads.
