Würth Elektronik MagI³C-FIMM Fixed Isolated MicroModule

Würth Elektronik has launched the MagI^³C-FIMM Fixed Isolated MicroModule. It combines the features of an isolated power module with those of a MicroModule in an LGA-7 package and measures 9 x 7 x 3.1 mm. The isolation capacitance between the primary and secondary windings is just 8 PF. The 1 W output power is maintained up to an ambient temperature of 100°C without derating. It also features an efficiency up to 91%.

The fixed isolated MicroModule features a fully integrated DC/DC converter with switching power stage, controller, and inductor as well as input/output capacitors. It requires no external circuitry — all components, including CIN and COUT, are integrated, allowing quick and easy circuit design without transformer expertise.

The MicroModule features a small size and is designed to provide high efficiency, as well as an extended operating ambient temperature range up to 125°C. The module offers continuous short-circuit protection and overvoltage protection up to 3000 V.

The module is suitable for applications in data acquisition, test and measurement technology, for supplying interfaces and microcontrollers, and other requirements in industrial electronics. It provides functional isolation for overvoltage protection and minimises ground loops and ground shifts as well as noise in the signal path or sensor systems. Per the manufacturer’s measurements, the low radiated EMI with tested filter combination is below the EN55032 Class B/CISPR-32 limits. The module is certified according to the current UL standard UL62368-1.

Developers can now order free samples and an evaluation board is available. The module is available from stock without a minimum order quantity.
