TEA1721 Non-Isolated Buck/Boost Converter Demo Board

TEA1721ADB1060

画像にカーソルを合わせると拡大表示されます。

This board demonstrates a +12 V AC/DC buck and −12 V AC/DC non-isolated buck/boost-mode SMPS that can be used to supply up to 2.5 W into a load. Operation in buck or buck/boost-mode can be selected with the on-board jumper.

The switch mode converter operates at a maximum frequency of around 50 kHz.

Overcurrent and short-circuit protection are built in. Under no-load conditions, the power consumption of this converter is in the range of 10 mW. EMI filtering and (optional) surge voltage protection using TVS diodes is implemented in this circuit.
