Integrated Circuit  
Dual Channel Current Mode Controller  
Description:  
The NTE1765 is a high performance, fixed frequency, dual current mode controller in a 16–Lead DIP  
type package. This device is specifically designed for Off–Line and DC to DC converter applications  
offering the designer a cost effective solution with minimal external components. The NTE1765 fea-  
tures a unique oscillator for precise duty cycle limit and frequency control, a temperature compen-  
sated reference, two high gain error amplifiers, two current sensing comparators, drive output 2 en-  
able 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.  
Features:  
D Unique Oscillator for Precise Duty Cycle Limit and Frequency Control  
D Current Mode Operation to 500kHz  
D Automatic Feed Forward Compensation  
D Separate Latching PWMs for Cycle–By–Cycle Current Limiting  
D Internally Trimmed Reference with Undervoltage Lockout  
D Drive Output 2 Enable Pin  
D Two High Current Totem Pole Outputs  
D Input Undervoltage Lockout with Hysteresis  
D Low Start–Up and Operating Current
