DC/DC converters suit IGBT drive applications

The encapsulated devices are suitable for powering high and low side gate drives in bridge circuits using IGBTs and MOSFETs. Offering basic and supplementary insulation, with an isolation test voltage of 5.2kVDC, the converters conform to the internationally recognised safety standard UL60950. Available in an industry standard SIP format, they occupy a 1.96cm2 footprint and achieve a power density of 0.81W/cm2. The series comprises 12 models offering nominal input voltages of 5, 12, 15 or 24VDC. For each input voltage there are three output voltage combinations available: +15/-5VDC, +15/-8.7VDC or +20/-5VDC. The converters 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.
