The DC-DC Step-down Converter Module with the LM2596S chip allows you to convert the voltage from the range of 3-40 V to a regulated output voltage of 1.5-35 V with high efficiency up to 92%. The maximum output current is 3 A, and the operating frequency is 150 kHz. The compact design with dimensions of 43 × 21 × 14 mm, the possibility of precise voltage regulation and a pinout of 2.54 mm facilitate the integration of the module in DIY projects, power supply systems, modeling and laboratory stations. The operating temperature range is from -40 to 85°C

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 6 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.

This synchronous switching step-down (or buck) regulator takes an input voltage of up to 40 V and efficiently reduces it to 6 V with an available output current of around 15 A. Pololu 2882
