60 V input buck with synchronous rectification
The MAX17506ATP+T is a step-down (buck) switching regulator from the Analog Devices Himalaya series, delivering a positive adjustable output from a 4.5 V to 60 V input rail. The integrated synchronous rectifier eliminates the external catch diode, reducing BOM count and board area in the 20-TQFN (5x5 mm) package.
Wide input range and adjustable output
The output adjusts from a 0.9 V minimum up to 54 V maximum, set by an external resistor divider — the same BOM serves multiple output voltages across a design family. Switching frequency is programmable from 200 kHz to 2.2 MHz via a single resistor. Lower frequencies reduce switching losses for high step-down ratios; higher frequencies shrink the inductor and output capacitor footprint at the cost of increased FET losses.
