NTE7125 & NTE7126
Integrated Circuit
Switching Regulator
Description:
The NTE7125 and NTE7126 are integrated circuits in a 12–Lead SIP type package incorporating all
the power switching, amplifier, error detection, and overcurrent protection circuits required in a self–
extcitation type semi–regulated off–line switching regulator. As a result, these devices can be used
in the design of switching power supplies with a minimal number of external components. Further-
more, the adoption of MOSFET power switching elements supports a higher oscillation frequency
than possible with bi–polar transistors. This allows smaller pulse transformers and capacitors to be
used, making it possible to construct miniature power supply systems.
Features:
D Power MOSFET Devices
D Ideal for Semi–Regulated Control Switching Supplies
D Error Detection Circuit On–Chip (40.5V ±0.5V Set Refernce Voltage)
D Overcurrent Protection Circuit On–Chip
D Higher Oscillation Frequency allows the use of Smaller Pulse Transformers
D IMST Substrate acts as an Electromagnetic Shield, makinf Low–Noise Designs Possible
Applications:
D CRT/CTV Power Supplies
D Office Automation Equipment Power Supplies
