Order this document by MC34067/D High Performance Resonant Mode Controllers The MC34067/MC33067 are high performance zero voltage switch resonant mode controllers designed for off–line and dc–to–dc converter applications that utilize frequency modulated constant off–time or constant deadtime control. These integrated circuits feature a variable frequency oscillator, a precise retriggerable one–shot timer, temperature compensated reference, high gain wide bandwidth error amplifier, steering flip–flop, and dual high current totem pole outputs ideally suited for driving power MOSFETs. Also included are protective features consisting of a high speed fault comparator, programmable soft–start circuitry, input undervoltage lockout with selectable thresholds, and reference undervoltage lockout.
