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 --25C to +125C
Shutdown Capability
Over Temperature Protection
Optional/Adjustable Frequency Clamp to Limit EMI
This is a Pb--Free and Halide--Free Device
