PMP10977, 4-20 mA Loop Sensor Isolated Power Supply

PMP10977, 4-20 mA Loop Sensor Isolated Power Supply. The TPS54061 is used in a buck topology with an auxiliary winding providing power to the primary side and isolated side of a isolated system. The high efficiency of this topology provides more output current from a system powered from a current limited input source. The isolated output is post regulated with an LDO for best regulation
