LM2586 SIMPLE SWITCHER 3A反激式稳压器,带有关断 LM2586 SIMPLE SWITCHER 3A Flyback Regulator with Shutdown
DESCRIPON
The LM2586 series of regulators are monolithic integrated circuits specifically designed for flyback, step-up boost, and forward converter applications. The device is available in 4 different output voltage versions: 3.3V, 5.0V, 12V, and adjustable.
Requiring a minimum number of external components, these regulators are cost effective, and simple to use. Included in the datasheet are typical circuits of boost and flyback regulators. Also listed are selector guides for diodes and capacitors and a family of standard inductors and flyback transformers designed to work with these switching regulators.
