Isolated Power Supplies for Telecom Applications

Abstract: Simple easy to use high side current sense amps protects power supplies as a result of irregular
supply voltage caused by short-circuit conditions.


To ensure compliance with all international standards, the designer of an isolated power supply for telecom
applications needs to take certain facts into account: The input voltage is never 110V or 220V from the mains,
but the lower voltage of a lead-acid battery (-12V, -24V, or -48V)
