Cart Description
PMP717 is a low cost, isolated, non-synchrounous 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 3.3V at 1.5A from the 48V PoE input. The design is optimized for low cost and smallest board area possible.
