MC33362DW - Brand New onsemi AC DC Converters, Offline Switchers
-
Description
The MC33362DW is a high-voltage switching regulator designed to work from a rectified 120 VAC line source. It is an AC/DC converter and offline switcher. This integrated circuit offers a wide range of features including an on-chip 500 V/2.0 A SENSEFET power switch, 250 V active off-line startup FET, duty cycle-controlled oscillator, current limiting comparator with programmable threshold and leading-edge blanking, latching pulse width modulator for double pulse suppression, high gain error amplifier, and a trimmed internal bandgap reference. It also has protective features such as cycle-by-cycle current limiting, input undervoltage lockout with hysteresis, output overvoltage protection, and thermal shutdown. The MC33362DW is available in a 16-lead dual-in-line and wide body surface mount package.
