Product Details
__
High Safety Latched Mode Greenline™ PWM Controller for (Multi)Synchronized Applications
**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
