LM2587 Adjustable 5A Flyback Voltage Regulator – Datasheet

3,069 views

The LM2587 regulator is a monolithic integrated circuit are 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, this regulator is 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.
