High Performance
Dual Channel Current
Mode Controllers
The MC34065−H,L series are high performance, fixed frequency,
dual current mode controllers. They are specifically designed for
off−line and dc−to−dc converter applications offering the designer a
cost effective solution with minimal external components. These
integrated circuits 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.
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.
These devices are available in dual−in−line and surface mount
packages.
The MC34065−H has UVLO thresholds of 14 V (on) and 10 V (off),
ideally suited for off−line converters. The MC34065−L is tailored for
lower voltage applications having UVLO thresholds of 8.4 V (on) and
7.8 V (off).
