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.
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.
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.
