LM2596S 3A DC-DC Step Down Buck Converter 3.3V Fix Out Regulator UBEC - 3.3V 3A

This is an LM2596 DC-DC buck converter step-down power module with a high-precision potentiometer, capable of driving a load up to 3A with high efficiency, which can work with Freeduino UNO, other mainboards, and basic modules. When the output current keeps greater than 2.5A, please add a heat sink to it. This device is internally compensated to minimize the number of external components to simplify the power supply design. Since the LM2596 converter is a switch-mode power supply, its efficiency is significantly higher in comparison with popular three-terminal linear regulators, especially with higher input voltages. The LM2596 operates at a switching frequency of 150 kHz thus allowing smaller-sized filter components than what would be needed with lower frequency switching regulators.
