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.
