HV461 Ring Generator Controller IC

The HV461FG is a highly integrated ring generator controller IC, designed to work with a patented four-quadrant inverter topology, with synchronous rectifiers on the secondary side to achieve higher efficiencies. The inverter delivers the desired ring voltage from a standard -48V Telecom power suppl.
