D8639F is a smart secondary-side
isolated fly-back system. The IC emulate the behavior of
Schottky diode rectifier for reduces power dissipation.
D8639F works in CCM/DCM and
Ruggedness and noise immunity are accomplished
an advanced blanking scheme and double
suppression which allow reliable operation in all operating
modes.
D8639F senses the build-in
voltage, and output ideal drive signal
components. It can support wide rang of system output
voltage 5V~12V。.
