This series of high-isolation DC-DC converters is designed to power both the high and low gate driver circuits of IGBTs, silicon carbide (Sic) MOSFETs in bridge circuits used in motor control applications and industrial power installations. Rated at 6 W, the dual-output converters provide a wide 2:1 input voltage range with nominal values of 5, 12, and 24 V, and output voltages of 15/-10 V, 20/-5 V, and 15/-5 V.
Asymmetrical outputs are suitable for power applications requiring a DC connection voltage up to 3 kVDC, and they provide an optimal drive level to maintain high system efficiency with low EMI levels. Their frequency, synchronization capability, and low coupling capacitance, typically 13 pF, facilitate EMC compliance.
The converters' compact design reduces board space and development time, while their 80 kV/microsecond dV/dt immunity provides users with confidence in long-term durability. Furthermore, the use of planar magnetic technology enhances product reliability and performance repeatability. Common applications include motion control/motor drive, solar inverters, UPS systems, alternative energy (wind generators), higher-power AC-DC conversion, EV/HEV traction, and welding.
The MGJ6 series of converters offers an operating temperature range of -40 to 105°C, with a derating above 90°C. Standard features of these patent-protected converters include an enable pin, short-circuit and overload protection, and a frequency synchronization pin that simplifies EMC filter design.
The series is pending IEC 61800-5-1 approval based on a high operating voltage of 690 Vrms maximum between primary and secondary, while also pending UL approval for UL 60950 for reinforced insulation with an operating voltage of 690 Vrms.
