! " the mc44605 is a high performance current mode controller that is specifically designed for offline 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 cyclebycycle 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 ? softstart 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 reapplying power greenline is a trademark of motorola, inc. this document contains information on a product under development. motorola reserves the right to change or discontinue this product without notice. ? motorola, inc. 1996 issue 0
