Dual-output DC/DC converters

29 October 2014 Power Electronics / Power Management

The MGJ2 series of 2 Watt, dual-output DC/DC converters, new from Murata Power Solutions, is suitable for powering high- 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 d.c. and conforming to the internationally recognised safety standard UL60950 (certification pending), the encapsulated devices can provide a key element of the end-product’s safety insulation system. Certification to the medical safety standard UL60601 (3rd edition) is also pending.

Packaged in an industry-standard SIP format, they occupy a 1,96 cm squared footprint and achieve a power density of 0,81 W/cm³. The series comprises 12 models offering nominal input voltages of 5, 12, 15 or 24 V. For each input voltage there are three output voltage combinations available: +15/-5 V, +15/-8,7 V or +20/-5 V.

The converters have a characterised dv/dt immunity, suiting reliable operation in fast switching applications. Partial discharge performance is also optimised 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.
