I am debugging a LLC circuit with UCC256302.
when light load (100mA), it is normal with 24V output and burst mode.
when no load, the output is 17.6V and VCC voltage is14.3V.
low side mos driver is continuous mode with 10% duty and 6.4kHz frequency.
could you advise some tips to me? what reason does cause the problems? thanks a lot.
