DALLAS, Oct. 8, 2012 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NASDAQ:TXN) today introduced two power management integrated circuits that combine a Power over Ethernet powered device (PD) manager with a DC/DC controller. The TPS23751 and TPS23752 controllers deliver high conversion efficiency over a wide load range and light load efficiency that is 20-percent higher than other solutions on the market. These ICs are designed for use in IEEE 802.3at type 2 (high-power) compliant PoE designs, used in IP phones, surveillance cameras, wireless access points, as well as various industrial applications. For more information and to order samples, visit: www.ti.com/poe-pr.
The new PoE solutions join TI's family of PD controllers, including the TPS2378 and TPS2379. The TPS2378 features IEEE 802.3 type 2 compliance and is interoperable with the UPOE Ethernet implementation, which delivers 25.5 W to 51 W over Ethernet CAT-5 cables utilizing the four-pair technique. The TPS2379 delivers higher output power capability with the addition of an external FET to control loads from 50 W to 100 W.
Key features and benefits of TPS23751 and TPS23752:
