The MGJ6 series has characterised partial discharge performance, crucial to achieving a long service life in high-performance applications.
Murata has extended the MGJ6 series of isolated 6W dual output DC-DC converters from Murata Power Solutions. Optimised to suit the bipolar voltages required for high-side and low-side IGBT, SiC, and MOSFET gate drive applications, Murata's MGJ6 series is available in SIP, DIP, and a low profile surface mount package format.
The series comprises combinations of wide input voltages with nominals of 5, 12, or 24 VDC and +15 / -5, +15 / -10 or +20 / -5VDC outputs. Suitable for low to medium power applications that require a DC link voltage up to 3kVDC, the asymmetric outputs provide optimum drive levels to maintain a high system efficiency with low EMI levels. Also, with its very low coupling capacitance, typically 15pF EMI coupling through the converter is reduced.
The MGJ6 series has a characterised dV/dt immunity of 80kV/us minimum at 1.6kV, contributing to a high degree of reliability in fast switching drive systems. The series also has characterised partial discharge performance, crucial to achieving a long service life in high-performance applications.
Certification to safety standard UL60950 for reinforced insulation and the medical 3rd edition safety standard ANSI/AAMI ES60601-1 for 2 MOOPs and 2 MOPPs is currently pending. With a creepage and clearance of 8mm, the MGJ6 will satisfy safety agency requirements for extra-high working voltages.
Short circuit and overload protection features are standard across the range and a frequency synchronisation/enable input pin can simplify EMC filter design.
