So for my application I am using the PT4523 DC DC (12V 20W 48V-Input Isolated DC/DC Converter) and to switch the DC DC on and off , I have used the optocoupler tclt1103. The input signal to the optocoupler is 3.3V and the limiting resistor is 1.5K from a MCU.
It works fine for a while and then the DC DC stops responding. When the optocoupler is taken off, the DC DC starts to work.
What parameters should I be looking into in the datasheet?
