High Performance Resonant Mode Controller
MC34067, MC33067
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 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.
