STMicroelectronics STEVAL-POE003V1 Evaluation Board
STMicroelectronics STEVAL-POE003V1 Evaluation Board is designed to evaluate the PM8804/5. The STMicroelectronics PM8804/5 is an IEEE 802.3bt PoE-PD interface with a system-in-package for smart power supplies. The PoE interface is based on the PM8805 PoE-PD interface and a DC-DC forward active clamp converter is based on the PM8804 controller. The STEVAL-POE003V1 targets high-efficiency conversion over a wide load range.
Features
