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. High efficiencies are maintained at light loads by dynamically changing the switching frequency, and an optional shutdown pin enables a low-power state with a current draw of a few hundred microamps.

The S7V7F5 switching step-up/step-down regulator efficiently produces 5 V from input voltages between 2.7 V and 11.8 V. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below 5 V. The very compact (0.35″ × 0.475″) module has a typical efficiency of over 90% and can supply up to 1 A when stepping down and about 500 mA when stepping up.

This tiny (0.35″×0.45″) U1V10F5 switching step-up (or boost) voltage regulator efficiently generates 5 V from input voltages as low as 0.5 V. Unlike most boost regulators, the U1V10F5 automatically switches to a linear down-regulation mode when the input voltage exceeds the output. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.

The S7V8F5 switching step-up/step-down regulator efficiently produces a fixed 5 V output from input voltages between 2.7 V and 11.8 V. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below the regulated voltage. The compact (0.45″ × 0.65″) module has a typical efficiency of over 90% and can deliver 500 mA to 1 A across most of the input voltage range.

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 50 V and efficiently reduces it to 5 V. The board measures only 0.7″ × 0.8″ yet delivers typical maximum continuous output currents between 2.5 A and 4 A, depending on the input voltage, which makes it well suited for powering moderate loads like sensors or small motors

This male JST RCY plug, also called a BEC connector, has 10 cm 20-AWG leads with stripped and tinned terminations. The connector is keyed so that power cannot be reversed.

This synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 5 V while allowing a typical continuous output current of up to 9 A. Typical efficiencies of 80% to 95% make this regulator well suited for higher-power applications like powering motors or servos, while high efficiencies are maintained at light loads by dynamically changing the switching frequency, and an optional shutdown pin enables a low-power state with a current draw of a few hundred microamps. The regulator’s output voltage setting can also be lowered by adding an external resistor.

The S7V8A switching step-up/step-down regulator efficiently produces an adjustable output between 2.5 V to 8 V from input voltages between 2.7 V and 11.8 V. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below the regulated voltage. The compact (0.45″ × 0.65″) module has a typical efficiency of over 90% and can deliver 500 mA to 1 A across most combinations of input and output voltages.

This powerful step-up/step-down regulator efficiently produces a fixed 5 V output from input voltages between 3 V and 30 V while allowing a typical output current of up to 2 A when the input voltage is close to the output voltage and offering typical efficiencies of 80% to 90%. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below the regulated voltage.
