Description

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.

Features

  • Compatible with Universal Mains 85 V (AC) to 265 V (AC)
  • Dual output voltage 12 V (DC) and 3.3 V (DC)
  • Primary side voltage regulation removes the need for an optocoupler
  • Total maximum power is 5 W
  • No-load power consumption of 20 mW
