| Overview |
1 (1) Zero Current Detect The ZCD Pin ensures critical conduction mode. ZCD monitors the voltage on the auxiliary winding, during the demagnetization phase of the transformer, comparing it to an inter.
an on- board reference, UVLO function, a watchdog timer to initiate output switching, a zero current detector to ensure critical conduction operation, a current sensing comparator, leading edge blanking, a CMOS driver and cycle- by- cycle current limiting. The MC33364D1 has an internal 126 kHz frequ.
