NTE7125中文资料NTE数据手册PDF规格书

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
