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. Furthermore, 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:
● Power MOSFET Devices
● Ideal for Semi–Regulated Control Switching Supplies
● Error Detection Circuit On–Chip (40.5V ±0.5V Set Refernce Voltage)
● Overcurrent Protection Circuit On–Chip
● Higher Oscillation Frequency allows the use of Smaller Pulse Transformers
● IMST Substrate acts as an Electromagnetic Shield, makinf Low–Noise Designs Possible

APPLICATIONs:
● CRT/CTV Power Supplies
● Office Automation Equipment Power Supplies
