Description

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 and latch, programmable soft-start circuitry, inputundervoltage lockout with selectable thresholds, and reference undervoltage lockout.These devices are available in dual-in-line and surface mount packages.
