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 parator, leading edge blanking, and a CMOS driver. Protection features include the ability to shut down switching, and cycle- by- cycle current limiting. The MC33364D1 is available in a surface mount SO- 8 package. It has an internal 126 k Hz frequency clamp. For loads which have a low power operating condition, the frequency clamp limits the maximum operating frequency, preventing excessive switching losses and EMI radiation. The MC33364D2 is available in the SO- 8 package without an internal frequency clamp. The MC33364D is available in the SO- 16 package. It has an internal 126 k Hz frequency clamp which is pinned out, so that the designer can adjust the clamp frequency by connecting appropriate values of resistance.
