STEVAL-POE005V1: 12V @ 8A, IEEE 802.3bt Power Over Ethernet (PoE)
The STEVAL-POE005V1 reference design represents a 3.3 Volt at 20 Amp Power over Ethernet converter solution, ideal for various applications including wireless access points, supplied with a PoE-PD interface and a DC-DC active clamp forward converter.
The PoE-PD interface is based on the PM8805 system in package device with two active bridges and an IEEE 802.3bt Type 4 compliant Powered Device (PD) interface. It can be used in all medium-to-high power 2P and 4P high efficiency PoE and PoE+ applications.
The DC-DC active clamp forward converter is designed around the PM8804 PWM controller, which is an integrated solution for smart and efficient 48 V converters, featuring a programmable oscillator for the switching frequency, adjustable slope compensation, dual complementary low-side drivers with programmable dead time, programmable soft start, soft turn off and a programmable current sense blanking time.
