This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 36 V and efficiently reduces it to 9 V. The board measures only 0.7″ × 0.7″ yet delivers typical continuous output currents between 1.5 A and 2.3 A, depending on the input voltage, which makes this regulator 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 5 µA to 10 µA per volt on VIN. The regulator also features reverse voltage protection and a power-good output indicates when the regulator cannot adequately maintain the output voltage.
