This powerful step-up/step-down regulator efficiently produces an adjustable 4 V to 12 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%.
This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 3.3 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 80% to 95% make this regulator well...
The S9V11F5 switching step-up/step-down regulator efficiently produces 5V from input voltages between 2V and 16V. Pololu 2836
