TOP271VG

Hi
About TOP271VG, the maximum drain current before IC goes to shun down what I measured is about 3A (DCM_ flyback) peak,
but spec. is around 5A, am I right? I do reduce RIL from 5K to even 1K ohmic, I still can't increase maximum drain current.
I need peakload for capacitance load test(around 6600uF), my board is design 60Volts DC output. Do you have any idea to add a circuit to overcome it?

Hi,
Can you please share the power supply schematic, PIExpert/PIXls design document and as well as transformer construction document?
