Order this document by MC33364/D MC33364 Advance Information Critical Conduction GreenLine? SMPS Controller CRITICAL CONDUCTION The MC33364 series are variable frequency SMPS controllers that operate in the critical conduction mode. They are optimized for low power, high density GREENLINE? SMPS power supplies requiring minimum board area, reduced component count, CONTROLLER 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 SEMICONDUCTOR power compared to resistor bootstrapped circuits. TECHNICAL DATA 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,
