Pololu Buck Regulator, Vin 4.5-50V, Vout 3.3V 3.6A

This small synchronous switching step-down (or buck) regulator takes an input voltage from 4.5 V to 50 V and efficiently reduces it to 3.3 V. The board measures only 18 x 20mm yet delivers typical maximum continuous output currents between 3.2 A and 4.5 A, depending on the input voltage, which makes it well suited for powering moderate loads like sensors or small motors. An optional enable input can be used to put the regulator in a low-power state with a current draw of 10 µA to 20 µA per volt on VIN. The regulator also features reverse voltage protection and a power-good output that indicates when the regulator cannot adequately maintain the output voltage. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.
