General description
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 is a power supply for a desktop PC.
The TEA1781T and TEA1782T are secondary control ICs and regulate each output
voltage independently of the primary duty cycle and other secondary output
voltages.
Because of these separated regulations, the system doe...
