Additional Information

The MC33370 is a monolithic high voltage power switching regulator that combines the required converter functions with a unique programmable state controller, allowing a simple and economical powersystem solution for office automation, consumer, and industrial products.

These devices are designed to operate directly from a rectified AC line source, and in flyback converter applications are capable of providing an output power in excess of 150 W with a fixed AC input of 100 V, 115 V, or 230 V, and in excess of 90 W with a variable AC input that ranges from 85 V to 265 V.

This device series features a programmable state controller, an on-chip 700 V SENSEFETE power switch circuit, 700 V active off-line startup circuit including a high voltage JFET and a low voltage MOSFET, auto restart logic, fixed frequency duty cycle controlled oscillator, current limiting comparator with leading edge blanking, latching pulse width modulator for double pulse suppression, and a high gain amplifier with a bandgap reference. Protective features include cycle-by-cycle current limiting, input undervoltage lockout with hysteresis, and a non-latching thermal shutdown.
