## Description

Selection and identification of the PWM controller AC/DC converter by pin.<br>Every master involved in repair of electronic equipment, in particular repairs pulse power supplies, met with problems of identifying or selecting an analogue of a PWM controller chip that had evaporated or burst into small pieces.<br>Usually, the repair begins with drawing a diagram of the power supply, and this is where it ends, since downloading hundreds of datasheets and comparing them with the resulting diagram will take a long time.<br>Since every AC/DC PWM controller has the following pins:<br>- microcircuit supply voltage;<br>- common;<br>- Feedback;<br>- power transistor supply;<br>- not connected, not used;<br>- power transistor control;<br><br>This application will help in a matter of seconds to identify or select a PWM controller microcircuit, just select the pin numbers in the header according to their functional purpose.<br>Today the database contains 972 PWM controller names.
