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 internal reference.

The ZCD sets the latch for the output driver.

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 frequency clamp. The MC33364D2 is available without an internal frequency clamp. The MC33364D has an internal 126 kHz frequency clamp which is pinned out, so that the designer can adjust the clamp frequenc.
