PMP10055, 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 9W peak power
