Output voltage is adjustable from 0.8 V up to 54 V via an external resistor divider, and the part uses synchronous rectification — the internal low-side FET replaces the usual catch diode, which keeps efficiency above 85 % across most of the load range and eliminates the external Schottky from the BOM. The switching frequency is programmable from 100 kHz to 2.2 MHz via a single resistor. A 400 kHz setting keeps the inductor small while staying clear of AM-band noise; 2.2 MHz pushes the switching harmonics above the EMI compliance band for sensitive receiver front-ends. ## Package and board-fit — 10-TDFN with exposed pad The 3x2 mm footprint suits space-constrained designs on 2-layer boards; the paddle's thermal vias should connect to an inner ground plane for heat spreading. ## Lifecycle and compliance — active, ROHS3, no second-source The Himalaya series includes higher-current siblings, but none are pin-compatible with this 10-TDFN layout; a board spin would be required for a different current rating.","metaTitle":"MAX17551ATB+T Analog Devices Himalaya Buck, 50 mA, 60 V","metaDescription":"MAX17551ATB+T Analog Devices Himalaya step-down regulator, 50 mA output, 4-60 V input, adjustable output, 10-TDFN.
