The NTE7125 and NTE7126 are integrated circuits in a 12Lead SIP type package incorporating all the power switching, amplifier, error detection, and overcurrent protection circuits required in a self extcitation type semiregulated offline 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 bipolar transistors. This allows smaller pulse transformers and capacitors to be used, making it possible to construct miniature power supply systems. Features: |
