NTE NTE7002 - Switching Power Supply Control IC SIP-9

The NTE-7002 is a bipolar IC in a 9-pin SIP type package that drives, regulates and monitors the switching transistor in a power supply based on the flyback principle of the ringing choke. Due to the wide regulation range and high voltage stability during large load changes, switching power supplies for Hi-Fi equipment and active speakers can be realized as well as applications in TV receivers and VCRs.
Features :
Wide operating range
High voltage stability even under high load changes
Direct control of the switching transistor
Low starting current
Linear folding of the overload characteristic
Basic control proportional to the current flowing through the power switching transistor
3.5W standby mode in external charging
Inhibiting capability (TTL compatible)
Undervoltage lockout
