Overview
| Topology | Flyback Converter |
| Input voltage | 42.5-57 V |
| Output 1 | 5 V / 6 A |
| IC revision | F |
Description
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.
Features
- Redundant inputs: two PoE and 48V adapter
- Continuous output when switching between inputs
- 84% efficiency with 5V/6A output and PoE input
Typical applications
- Outdoor backhaul unit / Small cell base station / WLAN/Wi-Fi access point
