Part Details for LM340 by National Semiconductor Corporation

This industrial charger reference design uses the LM5023 Quasi-Resonant Flyback controller to implement a 120VAC input design with CVCC output configured by microcontroller PWM control from 10 to 22.5V and output current from 200mA to 2A.

This Power over Ethernet (PoE) reference design supplies power and data over a single Ethernet cable to a connected LED lighting ballast. This reference design uses TI's TPS2372-4 PoE powered device (PD) interface: LM3409 buck controller: LM5165 buck converter: TPS62740 buck converter: TM4C1292NCPDT microcontroller (MCU): TPD4E05U06-Q1 ESD protection device: and DP83822I Ethernet PHY to provide power to the LED light remotely controlling the brightness and dimming parameters of the LED light while connected to the network. In need of an IEEE802.3bt-ready PSE controller? Check out the TPS23881.

This DLP3034-Q1 electronics reference design drives a DLP projector that can illuminate a phosphor film embedded inside glass to create a transparent window display. The phosphor film is transparent under normal conditions but turns into a colorful display when excited with 405-nm light from the DLP3034-Q1 projector.
