Step-Down converter D36V50F6 with an output voltage of 6 V, an input voltage from 6.5 to 50 V and a maximum output current of 8 A. Pololu 4092

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.

The compact (0.4″ × 0.5″) D24V5F1 synchronous buck voltage regulator takes input voltages between 3 V and 36 V and efficiently reduces them to 1.8 V while allowing for a maximum output current of 500 mA. This regulator offers typical efficiencies between 75% and 90%. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.

The Step-Down D24V3F5 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 300 mA. Pololu 2098

An efficient step-down converter that reduces the input voltage to 5 V at a maximum current of 100 mA, offering high efficiency due to low quiescent current (<20 μA). It supports input voltages from 5 V to 65 V, has short circuit and overheating protection, making it a reliable and energy-efficient solution. Pololu 5363

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

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 9 V. The board measures only 0.7″ × 0.7″, but it allows a typical continuous output current of up to 2.5 A. Typical efficiencies of 85% to 95% make this regulator well suited for powering moderate loads like sensors or small motors.
