The HLK-PM01 is a small size low cost AC to DC converter which can take in 110V/220V AC at 50/60 Hz and give 5V 3W output. The module is can be used in designs which run on 5V and needs to be powered form the AC mains.
A Metal Oxide Varistor (MOV) is a protection component used in power supply circuits that is powered directly from AC mains. It is used to protect the circuit from high voltage spikes by varying its resistance.
6N139 is an optocoupler IC designed for isolating primary circuit and secondary circuit electrically but the pair of LED and photodiode - Darlington setup forms the triggering mechanism between the two sides.
ON Semiconductor released new Automotive Intelligent Power Modules (IPMs) that offer class-leading power density and improve overall performance in on-board charging (OBC) and other high-voltage DC-DC conversion applications for ele
LM339 is a voltage comparator IC from LMx39x series and is manufactured by many industries. The devices consist of four independent voltage comparators that are designed to operate from a single power supply.
