MC33363DW中文资料安森美半导体数据手册PDF规格书

The MC33363 is a monolithic high voltage switching regulator that is specifically designed to operate from a rectified 240 Vac line source. This integrated circuit features an on−chip 700 V/1.0 A SENSEFET™ power switch, 450 V active off−line startup FET, duty cycle controlled oscillator, current limiting comparator with a programmable threshold and leading edge blanking, latching pulse width modulator for double pulse suppression, high gain error amplifier, and a trimmed internal bandgap reference. Protective features include cycle−by−cycle current limiting, input undervoltage lockout with hysteresis, output overvoltage protection, and thermal shutdown. This device is available in a 16−lead dual−in−line and wide body surface mount packages.
