Description

  • PMP5435, is an offline power supply that provides 50 watts of output power to two outputs. The outputs are 5 volts at 5 amps and 50 volts at 0.5 amps. A flyback topology is used to provide isolation from the high voltage in to a 12 and 48 volt output. The 5 volts is provided by a buck regulator powered from the 12 volts. There is also a serial data power provided that allows the monitoring of current, voltage and temperature information
