Introducing Murata’s DCDC converters for powering gate drive applications

MGJ6 Series

Murata introduced the MGJ6 Series of DC\DC power supplies for Multi-output DCDC converters providing a unique miniaturised solution to reduce design complexity and time-to-market.

IGBTs are commonly used in high power inverter and converter circuits and can require significant isolated gate drive power to switch optimally. Small isolated DC-DC converters can provide the power and performance characteristics needed to support the harsh requirements over alternative methods. The same considerations apply in principle to gate drives for silicon, silicon carbide and gallium nitride MOSFETs. The MGJ6Q, MGJ6T**F and MGJ6D**H series offer Three phase, Full bridge and Half Bridge options.
