Murata announces the MGJ2 series of 2 W high-isolation dual-output DC/DC converters from Murata Power Solutions. These compact encapsulated devices are suitable for powering "high side" and "low side" gate drives in bridge circuits using insulated-gate bipolar transistors (IGBTs) and MOSFETs. Offering basic and supplementary insulation, with an isolation test voltage of 5.2 kV_DC and conforming to the internationally recognized safety standard UL60950 (pending), the MGJ2 series can provide a key element of the end-product’s safety insulation system.

Packaged in an industry-standard SIP format, they occupy a 1.96 cm² footprint and achieve a power density of 0.81 W per cm³. The series comprises 12 models offering nominal input voltages of 5, 12, 15, or 24 VDC. For each input voltage there are three-output-voltage combinations available: 15/-5 VDC, 15/-8.7 VDC, or 20/-5 V_DC.

The converters have a characterized dv/dt immunity, suiting reliable operation in fast switching applications. Partial discharge performance is also optimized to give a long-service-life. The MGJ2 series has an extended operating temperature range of up to 100°C that suits industrial-grade temperature ratings. Typical applications include high-power AC/DC conversion, motor drives, and solar power inverters.
