The MC44605 is a high performance current mode controller that
is specifically designed for off–line converters. The MC44605 has
several distinguishing features that make it particularly suitable for
multisynchronized monitor applications.
The MC44605 synchronization arrangement enables operation from
16 kHz up to 130 kHz. This product was optimized to operate with
universal ac mains voltage from 80 V to 280 V, and its high current totem
pole output makes it ideally suited for driving a power MOSFET.
The MC44605 protections provide well controlled, safe power
management. Safety enhancements detect four different fault conditions
and provide protection through a disabling latch.
Current or Voltage Mode Controller
Current Mode Operation Up to 250 kHz Output Switching Frequency
Inherent Feed Forward Compensation
Latching PWM for Cycle–by–Cycle Current Limiting
Oscillator with Precise Frequency Control
Externally Programmable Reference Current
Secondary or Primary Sensing (Availability of Error Amplifier Output)
Synchronization Facility
High Current Totem Pole Output
Undervoltage Lockout with Hysteresis
Low Output dV/dT for Low EMI
Low Startup and Operating Current
Safety/Protection Features
Soft–Start Feature
Demagnetization (Zero Current Detection) Protection
Overvoltage Protection Facility Against Open Loop
EHT Overvoltage Protection (E.H.T.OVP): Protection Against Excessive
Amplitude Synchronization Pulses
Winding Short Circuit Detection (W.S.C.D.)
Limitation of the Maximum Input Power (M.P.L.): Calculation of Input
Power for Overload Protection
Over Heating Detection (O.H.D.): to Prevent the Power Switch from
Excessive Heating
Latched Disabling Mode
When one of the following faults is detected: EHT overvoltage, Winding
Short Circuit (WSCD), excessive input power (M.P.L.), power switch
over heating (O.H.D.), a counter is activated
If the counter is activated for a time that is long enough, the circuit gets
definitively disabled. The latch can only be reset by removing and then
re–applying power
