TEA1999TS USB BC1.2 Synchronous Rectifier Controller for Flyback
- This page contains information on a product that is no longer manufactured (discontinued). Specifications and information herein are available for historical reference only.
The TEA1999TS 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 TEA1999TS 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
