HIGH PERFORMANCE

DUAL CHANNEL CURRENT

MODE CONTROLLER

The MC34065 is a high performance, fixed frequency, dual current mode

controllers. It is specifically designed for off–line and dc–to–dc converter

applications offering the designer a cost effective solution with minimal

external components. This integrated circuit feature a unique oscillator for

precise duty cycle limit and frequency control, a temperature compensated

reference, two high gain error amplifiers, two current sensing comparators,

Drive Output 2 Enable pin, and two high current totem pole outputs ideally

suited for driving power MOSFETs.

SEMICONDUCTOR

TECHNICAL DATA

Also included are protective features consisting of input and reference

undervoltage lockouts each with hysteresis, cycle–by–cycle current limiting,

and a latch for single pulse metering of each output.

The MC34065 and MC33065 are available in dual–in–line and surface

mount packages.
