Application pour la sélection et l'identification des contrôleurs PWM par broches
Selection and identification of the PWM controller DC/DC converter by pin.
Every master engaged in the repair of electronic equipment met with the problem of identifying or selecting an analogue of a PWM controller chip that had evaporated or burst into small pieces.
Usually, the repair begins with painting the power supply circuit, and this is where it ends, since downloading hundreds of datasheets and comparing them with the resulting circuit will take a lot of time.
Typically, each DC / DC PWM controller has the following pins:
- Input and output voltage
- Feedback to stabilize the output voltage,
- Turn on / off the output voltage
- Common wire.
This application will help in a matter of seconds to identify or select a PWM controller microcircuit, just select the functional purpose of the pins in the header.
Today the database contains 680 PWM controller names.
The result can be printed directly from the application, or saved to a pdf file.
