Compact Isolated Power Modules: The MID Series

The Ideal Module Solution for Isolated Power Applications

MPS’s family of small, isolated power modules is perfect for biasing the digital isolators in RS485, RS232, and CAN communication, as well as other industrial and network applications. Higher channel density in PLC systems means less space per channel, making it critical for solutions to minimize board space. The MID power module family provides a tiny solution that integrates a transformer and a 5V isolated supply to power the digital isolator. Smaller than traditional SIP modules, these isolated power modules come in a mono-chip package, greatly improving robustness and reliability in harsh industrial environments. Excellent magnetic field immunity, higher production yield with automatic SMT machines, and easy solder inspection make this series perfect for isolated applications.
