Hello all,
Thanks for helping. I have been fighting with this circuit for a few days but I can't figure out what's wrong. It's a 12V flyback converter, I'm using LT8304 IC (doesn't require optocoupler or 3rd winding feedback) following the exact circuit and exact the same components from the datasheet (picture attached). It's a pretty simple circuit. I get the 12V at the output, It requires a minimum load to regulate (12mA, I have 1k resistor as load) but when I add more load(even another 1k resistor) the voltage drops and it's not delivering any current to the load. My input voltage is 30V.
I checked and replaced the output diode, added more capacitance to the output but nothing works.
Help will be much appreciated,
Regards,
Javier
