Description

The MC34065 is a high performance, fixed frequency, dual current modecontrollers. It is specifically designed for offline and dctodc converterapplications offering the designer a cost effective solution with minimalexternal components. MC34065 feature a unique oscillator forprecise duty cycle limit and frequency control, a temperature compensatedreference, two high gain error amplifiers, two current sensing comparators,Drive Output 2 Enable pin, and two high current totem pole outputs ideallysuited for driving power MOSFETs.

MC34065 include protective features consisting of input and referenceundervoltage lockouts each with hysteresis, cyclebycycle current limiting,and a latch for single pulse metering of each output.

The MC34065 and MC33065 are available in dualinline and surfacemount packages.
