Re: Ring generator for telecom

Thanks, I will check,

This is a product we do in small quantities. Now I am using a
transformer that has 2 outputs: 10V CA and 40V CA, the second one I´ve
made a simple charge pump to generate the ring, and also the line
voltage 40V CC.
It is cheap this way, works well. But I am thinking about making
something better, but not very expenive.

Thanks again for the info,

Does anyone knows a component, simple and not expensive for generating
the ringing voltage for a telephone? Something that would, with a few
external components raise the voltage from around 5V or 12V to the
ringing voltage of a telephone?
