MC33364 Critical Conduction GreenLine SMPS Controller

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. 3 (2) Current Sense The Current Sense P.

MC33364 Features

* 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
