High Voltage Power
Switching Regulator
The MC33369 through MC33374 are monolithic high voltage power
switching regulators that combine 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 SENSEFETpower 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. These devices are
available in economical 8–pin dual–in–line and five pin TO–220 style
packages.
