The MAX17632CATE+ is a step-down (buck) switching regulator from Analog Devices, delivering up to 2 A from a 4.5 V to 36 V input rail. The output is adjustable from 0.9 V up to 32.4 V, making it a flexible single-rail supply for industrial and automotive bias circuits. It integrates a synchronous rectifier, which eliminates the external Schottky diode and improves efficiency at higher switching frequencies. The switching frequency is programmable from 400 kHz to 2.2 MHz, allowing trade-offs between inductor size and switching losses.
Housed in a 16-lead TQFN (3 mm x 3 mm) with an exposed pad, the package requires a thermal land on the PCB to dissipate heat from the 2 A output. Supplied in a tube, the part is suitable for hand-assembly or low-volume reflow. The 16-WFQFN footprint is standard for this pinout; layout guidelines from the datasheet should be followed for the input and output capacitor placement.
