SparkFun MOSFET Power Switch and 3.3V Buck Regulator (Low-Side)

Description SparkFun MOSFET Power Switch and 3.3V Buck Regulator (Low-Side) Controls high-voltage items Powers up to 12V, 10A loads Stable 3.3V output Versatile connection options Onboard current measurement The SparkFun MOSFET Power Switch and 3.3V Buck Regulator (Low-Side) is designed to facilitate the control of high-voltage items, such as a 12V LED strip, while simultaneously providing power. This device is capable of powering a board with up to 12V and controlling a current of up to 10A, delivering a stable 3.3V to the control board. This product integrates an LMR14203 buck regulator, which is set to output 3.3V, and an N-channel MOSFET (PSMN7R0-100BS) that functions as a low-side switch. It includes a flyback diode on the load side to accommodate devices that generate back electromotive force. Activation of the load is achieved by pulling the CTL pin low. The device offers a variety of connectors, including a barrel jack, female header, and poke-home connectors,
