NTE7109 Détails du produit

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:

● 500kHz Operation to MOSFET

   • Output Current: ±2A

   • Output Rise Time: 60ns; Fall Time: 40ns

   • Modified Totem–Pole Output Method with Low Through Current

● 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

● 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 (OVP)

   • Protection Circuit for Output Miss Action at Low Supply Voltage (UVLO)

● High–Performance and Highly Functional Power Supply

   • Triangular Wave Oscillator for Easy Dead Time Setting



Applications:

• Feed Forward Regulator

• Flyback Regulator
