NTE7002
Integrated Circuit
Switched Mode Power Supply Control
9-PIN SIP
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:
- Wide Operational Range
- High Voltage Stability Even at High Load Changes
- Direct Control of Switching Transistor
- Low Start-Up Current
- Linear Foldback of the Overload Characteristic
- Base Drive Proportional to the Current Through the Power Switching Transistor
- Stand-By Mode 3.5W into the External Load
- Inhibit Capability (TTL Compatible)
- Undervoltage Lockout
