Pololu Buck Regulator, Vin 4.5-50V, Vout 3.3V 6.5A

This powerful synchronous switching step-down (buck) regulator takes an input voltage of up to 50V and efficiently reduces it to 3.3V. The board measures only 25.4mm x 25.4mm yet delivers typical maximum continuous output currents between 4.5A and 9.5A, depending on the input voltage, which makes it well suited for powering moderate to large loads. An optional enable input with a precise cutoff threshold 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.
