NTE7109

NTE7109 Integrated Circuit Switching Regulator Control Description: The NTE7109 is a primary switching regulator controller in a 16–Lead DIP type package designed to get the regulated DC voltage from an AC power supply. This device can directly drive a MOSFET with fast rise and fall output pulses. The NTE7109 contains not only a high frequency OSC and fast output drive, but also a current limiter with fast response and high sensibility so a true “fast switching regulator” can be realized. By adding additional compenents to the primary side, a timer–type protection circuit can be made for protection against short–circuit and overcurrent. Features: D 500kHz Operation to MOSFET Output Current: ±2A Output Rise Time: 60ns; Fall Time: 40ns Modified Totem–Pole Output Method with Low Through Current D Compact and Light–Weight Power Supply Low Start–Up Current: 90µA Typ. Wide Range Between “Start–Up Voltage” and “Stop Voltage” make the Power Input Smooting Capacitor Low; Start–Up Threshold Voltage: 16V; Stop Voltage: 10V High Power Dissipation Package withstands the Heat Generated bt the Gate–Drive Current of a MOSFET D Simplified Peripheral Circuit with Protection Circuit and Built–In Large–Capacity Totem–Pole Output High–Speed Current Limiting Circuit using Pulse–by–Pulse Method (Two Systems of CLM+pin, CLM–pin) Protection by Intermittent Operation of Output Overcurrent: Timer Protection Circuit Overvoltage Protection Circuit with an Externally Resettable Latch (OV...
