NTE7002

NTE7002 Integrated Circuit Switched Mode Power Supply Control Description: The NTE7002 is a bipolar integrated circuit in a 9–Lead SIP type package that drives, regulates, and monitors the switching transistor in a power supply based on the ringing choke flyback principle. Due to the wide regulating range and the high voltage stability during large load changes, SMPS for Hi–Fi equipment and active loudspeakers can be realized as well as applications in TV receivers and video recorders. Features: D Wide Operational Range D High Voltage Stability Even at High Load Changes D Direct Control of Switching Transistor D Low Start–Up Current D Linear Foldback of the Overload Characteristic D Base Drive Proportional to the Current Through the Power Switching Transistor D Stand–By Mode 3.5W into the External Load D Inhibit Capability (TTL Compatible) D Undervoltage Lockout Absolute Maximum Ratings: Supply Voltage, V9 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20V Sink Output Voltage V7 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0 to V9V V7–V8 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ±6V Reference Output, I1 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . ....
