<p>A DC to DC power converter for use within a transceiver module which connects a user host station, i.e., terminal, printer, workstation, etc., to an Ethernet coaxial cable. The converter, which may use an off-th-shelf switching regulator with accompanying circuitry (see Figure 1), provides adequately regulated DC output voltage and high voltage isolation between the Ethernet cable and the operating workstation. It utilizes fewer parts than known similar power supplies, and has soft start threshold provisions, overload protection, an LED performance indicator, and a trimmer for precise output voltage adjustment.</p> |
