Overview
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.
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.
