We have developed 2kW PFC Board with ICE3PCS01G.
When I did first power on with 12.15VDC, Vref not coming from IC. After that I replace the new chip, then it worked fine. But again after changing the nearest components during troubleshooting, the same problem came (vref gone), But ICOMP=5V is coming. 4 nos of IC got damaged and the same problem coming.
please suggest a solution.
Thanks for your Question. For the IC, the turn-on voltage is between 11.5~12.9V, turn of is between 10.5~11.9V. So, for 12.15V, if the Vcc is from 12.9V down to it, the IC will run. If VCC is from 10V up to 12.15V, the IC is off and can't work.
