Wide Input Range (140Vac to 440Vac) Non Isolated Off-line Flyback Converter with Multiple Outputs


An energy metering device very often needs non-isolated power: since the neutral is connected to the ground of the output. This is a typical application: when 1.8V: 3.3V: 12V and 18V are needed to supply digital and analog loads. Even though a small transformer is employed: the PSU delivers 9Wpeak power.
