1 Introduction
This reference design report describes a switched-mode power supply that was designed
to replace line frequency transformer based solutions. The supply uses a member of the
LinkSwitch-LP family of devices, and is capable of withstanding common-mode line
surges of up to 10 kV. That is often a requirement for applications that connect to a
telephone line, such as modems, cordless phones and answering machines.
The report includes the power supply specification, a circuit diagram, a bill of materials,
transformer documentation, a printed circuit layout board, and performance data.
