DCR011205U Vrec Voltage

Clark Leach

I don't see a spec in the data sheet regarding the voltage on this pin. Does anyone know the maximum voltage likely to appear on this pin? I am debating how best to pull it down in order to disable the output...

DCP011205U only method for disabling the secondary circuit is to use the enable function (pin 16) with a 10kΩ resistor isolating it from the Vrec pin, pin 12.

Then ground the Enable pin with a FET switch. The voltage on the Enable pin voltage when open is about 7V to 12V.
