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:
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: 90
μ
A 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
