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.
