Notas de aplicación
- Linear Technology Magazine Circuit Collection, Volume IV &mdash AN84PDF, 2.4 Mb, Archivo publicado: abr 1, 2000
Application Note 84 is a collection of "power circuits" from the years 1996 through 1998 as seen in the pages of Linear Technology magazine. This Application Note collects circuits that can output tens of amps to circuits that can operate a handheld device for several years. In addition to a wide variety of traditional power supply circuits (Buck, Boost, Inverting, Flyback, Linear Regulators, etc.) we include circuits for charging batteries, several Power Management circuits as well as circuits that highlight a very low noise switching regulator.Extracto del documento
