PMP940 描述
PMP940 is a high efficiency, isolated, synchrounous flyback Power-over-Ethernet PD power supply reference design intended to ease implementation of PoE in devices such as IP phones, WLAN AP's and security cameras. The reference design uses a TPS2375 PoE Powered Device Controller to implement all necessary detection, classification, inrush current limiting, UVLO and switch FET control necessary to be compliant with the IEEE802.3af Power-over-Ethernet standard. A UCC3809 Economy Primary Side Controller is used to generate 12V at 1A from the 48V PoE input. The design is optimized for maximum efficiency in the smallest board area possible.
