Board-mount isolated DC-DC converter provides dual port USB data isolation

Murata's NMUSB202MC surface-mount DC-DC converter module is now available from Farnell element14. The unit conveniently provides dual port USB data isolation from a single upstream port with full power (500mA) available from each downstream port. Isolation provides effective breaking of ground loops and immunity to EMI in harsh environments as found in industrial and medical applications. It has all the functions of a two-port isolated USB hub including isolated DC-DC converter in a 2.4cm x 2.4cm footprint. Full speed (12Mbps) and low speed (1.5Mbps) are supported with automatic switching. Input power of 5V is provided by an external 'adapter' or system voltage rail. The NMUSB202MC module's full compliance with USB 2.0 specification enables hassle-free 'plug and play' operation with any USB-compatible device, says the company.
