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
