The PN8386SEC-R1 from Chipown is a switching controller with an 8-pin SOP8 package that complies with RoHS standards for restricted use of hazardous substances. It is designed to perform voltage conversion and reverse polarity protection to prevent incorrect connections, and can deliver up to 1.5A at an output voltage range of 1.2-20V. The controller includes an enable pin that can be used to shut off power to the output when disabled, as well as an under voltage lockout that prevents the load from excessive current. It also has protection features such as over-current, over-temperature, and short-circuit protection to ensure reliability and safety while operating.
