TEA1781T Datasheet (NXP Semiconductors) - (TEA1781T / TEA1782T) GreenChip PC secondary control ICs

TEA1781T, (TEA1781T / TEA1782T) GreenChip PC secondary control ICs

The TEA1781T and TEA1782T are designed to cooperate with the TEA1771T primary side controller in a unique converter topology based on the active clamp forward converter.

On the secondary side the output voltages are regulated via bidirectional switches.

A typical application area of this converter i
