TEA1771 Datasheet (NXP Semiconductors) - GreenChip PC primary control IC

TEA1771, GreenChip PC primary control IC

The TEA1771 is a primary control IC for an active clamp forward converter.

This converter enables higher duty cycles of up to 70 %.

A higher maximum duty cycle lowers the required breakdown voltage of both the primary and secondary switches, reducing the total cost of the system.

The IC is optimized
