Beschreibung
- MAX5974CEVKIT#, Evaluation Kit (EV kit) is a fully assembled and tested surface-mount circuit board featuring the MAX5974C active-clamped, spread-spectrum, current-mode PWM controller for Power-over-Ethernet (PoE) powered device (PD) applications. The EV kit is a compact and low-cost design used in power-over-LAN (PoLAN) applications requiring DC power from an Ethernet network port for PDs such as IP phones, wireless access nodes, and security cameras. The EV kit features a galvanically isolated 25W, 250kHz switching-frequency, active-clamped, synchronous-rectified forward DC-DC converter using the IC. The device circuit achieves high efficiency up to 93.5% using a forward DC-DC converter topology. The surface-mount transformer provides up to +1500V galvanic isolation for the output. The EV kit output voltage is configured for +5V and provides up to 4.7A load current
