型號： NTE7109

類別： 集成電路

描述： 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 ?? ?
