MC33364

Critical Conduction

GreenLinet SMPS

Controller

The MC33364 series are variable frequency SMPS controllers that

operate in the critical conduction mode. They are optimized for high

density power supplies requiring minimum board area, reduced

component count, and low power dissipation. Integration of the high

voltage startup saves approximately 0.7 W of power compared to the

value of the 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, a CMOS driver and cycle−by−cycle current limiting.

The MC33364D1 has an internal 126 kHz frequency clamp. The

MC33364D2 is available without an internal frequency clamp. The

MC33364D 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.

Features

• Lossless Off−Line Startup

• Leading Edge Blanking for Noise Immunity

• Watchdog Timer to Initiate Switching

• Operating Temperature Range −25° to +125°C

• Shutdown Capability

• Over Temperature Protection

• Optional/Adjustable Frequency Clamp to Limit EMI

• Pb−Free Packages are Available
