45W / 19.5V Ultra book adapter.
45 W / 19.5 V Ultra Book Adapter
The TEA1833 demo board is a small and low cost solution for a 45W ultra book adapter or any low power adapter
solution.
The power supply can deliver a peak power up to 200 % for a limited amount of time.
The application is
EMI CISPR22, ENERGY STAR, DoE and CoC compliant. The used topology is fixed frequency flyback. The adapter has several
built-in protections and compensation features and excellent efficiency and standby power consumption performance.
