Selection and identification of the PWM controller AC/DC converter by pin.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.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.Since every AC/DC PWM controller has the following pins:- microcircuit supply voltage;- common;- Feedback;- power transistor supply;- not connected, not used;- power transistor control;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.Today the database contains 972 PWM controller names.
