2W DC/DC converters offer power density of 0.81W/cm3
High isolation dual output DC/DC converters, the MGJ2 series from Murata Power Solutions is suitable for powering “high side” and “low side” gate drives in bridge circuits using insulated-gate bipolar transistors (IGBTs) and MOSFETs. Packaged in an industry-standard SIP format, they occupy a 1.96cm2 footprint and achieve a power density of 0.81W/cm3.
The compact encapsulated devices have 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.
The series comprises 12 models offering nominal input voltages of 5, 12, 15 or 24V DC. For each input voltage there are three output voltage combinations available: +15/-5, +15/-8.7 or +20/-5V DC.
Offering basic and supplementary insulation, with an isolation test voltage of 5.2kVDC and conforming to the internationally recognised safety standard UL60950 (pending), the MGJ2 series can provide a key element of the end-product’s safety insulation system. Certification to the medical safety standard UL60601 3rd edition is pending.
