The NTE1765 is a high performance, fixed frequency, dual current mode controller in a 16Lead DIP type package. This device is specifically designed for OffLine and DC to DC converter applications offering the designer a cost effective solution with minimal external components. The NTE1765 features 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, cyclebycycle current limiting, and a latch for single pulse metering of each output.
