Main characteristics and circuit description
isolated voltage loop by the optocoupler U2, and using an inexpensive TL431 (U3) to drive
the optocoupler. The opto-transistor modulates the input voltage of the L6562A internal
amplifier, thus closing the voltage loop.
The output rectifier is a fast recovery type, selected according to its maximum reverse
voltage, forward voltage drop and power dissipation. A small LC filter is added on the output,
filtering the high frequency ripple.
The board is equipped with an input EMI filter designed for a 3-wire input mains plug. It is
composed of two, common mode Pi-filter stages connected after the input connector and
the input fuse. A varistor is also connected at the input of the board, improving immunity
against input voltage fast transients.
