Description
The PMP40144 is a 12V 2A reference design solution for PoE applications. The solution implements a high efficiency primary side controller UCC28704, eliminating feedback components(TL431, opto-coupler). The efficiency is >89% at full load. Integrated input UVLO, OVP and output OVP, OCP improves the power system reliability. The design is achieved in a compact form factor (68mm X 36mm X 15mm).
