Beschreibung

This reference design implements an IEEE802.3bt (draft) Power over Ethernet (PoE) Powered Device (PD) with dual redundant inputs and a smooth transition between these inputs and an auxiliary input. The design consists of a 5V/6A synchronous flyback converter and allows for up to three power supplies (two PoE Power Source Equipment (PSE) supplies 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.

Eigenschaften

  • Redundant inputs: two PoE and 48V adapter
  • Continuous output when switching between inputs
  • 84% efficiency with 5V/6A output and PoE input

Typische Anwendungen

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