MC44605
High Safety, Latched Mode,
GreenLine t PWM Controller
for (Multi) Synchronized
Applications
The MC44605 is a high performance current mode controller that is
specifically designed for off ? line converters. This circuit 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 mains voltage, i.e., 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 enable a well ? controlled and safe power
management. Four major faults while detected, activate the analogic
counter of a disabling block designed to perform a latched circuit

power switch overheating (O.H.D.), an analogic 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 making
decrease the V cc down to about 3.0 V, i.e., practically by unplugging
or turning off the SMPS.
