MC34067
feature a variable frequency oscillator, a precise retriggerable one- shot timer, temperature pensated 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 parator, 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.
