Beschreibung

This user manual describes the TEA1721 based 12 V and 3.3 V AC/DC SMPS demo board which provides 5 W into a load.

The switch-mode converter operates in flyback mode at a maximum frequency of around 50 kHz. Over-current and short circuit protection are built in.

Under no-load conditions, the power consumption of the flyback converter is around 20 mW. This application is typically suited for White Goods appliances and industrial applications.
