TEA1999DB1504

Roll over image to zoom in

The TEA1999TK add-on board is designed for incorporation into existing flyback power supplies, by replacing the secondary rectifier diode. The add-on board consists of the TEA1999TK SR controller IC and a low-ohmic MOSFET.

It can be used in all power supplies that require a high efficiency, like:
  • Chargers
  • Adapters
  • Flyback power supplies with very low and/or variable output voltage
