12V 1A Isolated PoE PD Power Supply Reference Design
PMP940: 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.
Isolated, Low Cost, Non-Synchronous PoE PD Power Supply Reference Design
PMP717: 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.
