Projekt referencyjny przez: Texas Instruments
PMP7993.1, Powering PLC I/O Module with LM5017 Fly-Buck. LM5017 Fly-Buck reference design provides multiple isolated outputs to supply bias voltage needed in a PLC I/O module. It generates 4 isolated outputs: 15V@50mA and 5V@100mA, it can cover most of required voltage rails in I/O module, such as Op-Amp, DAC bias, RS-485 transmitter and digital isolator power supplies. In Fly-Buck, regulation is done on primary side, and thus no Optocoupler is needed. overall load/line regulation for each output is within +/-5%. input voltage range is from 17V to 32V
