Texas Instruments TPS2373-4RGWR | Demoboard PMP21103

Beschreibung

This reference design implements an IEEE802.3bt compliant Class 5 Power over Ethernet (PoE) Powered Device (PD) with smooth transition between the PoE input and an auxiliary supply connected to the output. The design consists of a 12-V/2.5-A active clamp forward converter utilizing the UCC2897A controller and allows one PoE Power Source Equipment (PSE) supply and one AC/DC wall adapter auxiliary supply to be used in order to decrease the probability of power and data loss in your system. An IEEE802.3bt compliant TPS2373-4 high power PD controller is utilized to control all PoE functions.

Eigenschaften

• Smooth transition when switching between PoE input and 12-V adapter on output
• 89% efficiency with 12-V/2.5-A output and PoE input (FET OR-ing)
• Diode OR-ing option for lower cost

Typische Anwendungen

• Outdoor backhaul unit, Small cell base station, WLAN/Wi-Fi access point
