MC34067, MC33067, NCV33067 High Performance Resonant Mode Controllers The MC34067/MC33067 are high performance zero voltage switch resonant mode controllers designed for offline and dctodc converter applications that utilize frequency modulated constant www.onsemi.com offtime or constant deadtime control. These integrated circuits feature a variable frequency oscillator, a precise retriggerable MARKING oneshot timer, temperature compensated reference, high gain wide DIAGRAMS bandwidth error amplifier, steering flipflop, and dual high current totem pole outputs ideally suited for driving power MOSFETs. Also included are protective features consisting of a high speed fault 16 comparator and latch, programmable softstart circuitry, input 16 MC3x067P undervoltage lockout with selectable thresholds, and reference 1 AWLYYWWG PDIP16 undervoltage lockout. These devices are available in dualinline and P SUFFIX 1 surface mount packages.
