Category: Step-Down

This compact (0.4″ × 0.5″) switching step-down (or buck) voltage regulator takes input voltages up to 50 V and efficiently reduces them to 9 V while allowing for a maximum output current of 600 mA. It has a very low dropout, so it can be used with input voltages that are within a few hundred millivolts of its output.

The compact (0.4″ × 0.5″) D24V5F6 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 6 V while allowing for a maximum output current of 500 mA. Pololu 2844

The Step-Down D24V6F5 Buck Voltage Regulator module gives the output voltage of 5V with a wide input voltage range of 7-42V and a maximum output current of 600 mA. Pololu 2107

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 5 V. The board measures only 0.7″ × 0.8″, but it allows a typical continuous output current of up to 5 A. Typical efficiencies of 85% to 95% make this regulator well suited for high-power applications like powering motors or servos.
