MOTOROLA ANALOG IC DEVICE DATA
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, input undervoltage
lockout with selectable thresholds, and reference undervoltage lockout.
These devices are available in dual–in–line and surface mount packages.
