CRITICAL CONDUCTION  
GREENLINE SMPS  
CONTROLLER  
The MC33364 series are variable frequency SMPS controllers that operate  
in the critical conduction mode. They are optimized for low power, high density  
power supplies requiring minimum board area, reduced component count,  
and low power dissipation. Each narrow body SOIC package provides a small  
footprint. Integration of the high voltage startup saves approximately 0.7 W of  
power compared to resistor bootstrapped circuits.  
Each 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, and a CMOS driver. Protection features include the ability to shut  
down switching, and cycle–by–cycle current limiting.

TECHNICAL DATA  
8
The MC33364D1 is available in a surface mount SO–8 package. It has an  
internal 126 kHz 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.

PLASTIC PACKAGE  
CASE 751  
(SO–8)  
The MC33364D is available in the SO–16 package. It has an internal  
126 kHz frequency clamp which is pinned out, so that the designer can  
adjust the clamp frequency by connecting appropriate values of resistance.
