Integrated Circuit  
Switched–Mode Power Supply Controller  
Description:  
The NTE7117 is a control circuit in an 8–Lead DIP type package designed for use in switched–mode  
power supplies. It contains an internal temperature–compensated supply, PWM, sawtooth oscillator,  
over–current sense latch, and output stage. This device is intended for low cost SMPS applications  
where extensive housekeeping functions are not required.  
Features:  
D Pulse Width Modulator  
D Current Limiting (Cycle–by–Cycle)  
D Sawtooth Generator  
D Stabilized Power Supply  
D Double–Pulse Protection  
D Internal Temperature–Compensated Reference  
Applications:  
D Switch–Mode Power Supplies  
D DC Motor Controller Inverter  
D DC/DC Converter
