IGBT driver DC/DC converters deliver +15 VDC and -8 VDC

January 23, 2017 // By Julien Happich
MicroPower Direct's IG275E series of miniature DC/DC converters are designed specifically to provide the asynchronous output voltage levels required to properly bias the gate drive of IGBT semiconductors.

Offered at very low cost, three models operate from 12, 15 or 24 VDC input bus voltages, providing dual outputs of +15 VDC and -8 VDC; the recommended  gate bias levels for most IGBT driver circuits.

The output current is ±120mA. Standard features include 3,000 VAC I/O isolation, very low isolation capacitance and high efficiency. The MTBF (perMIL HDBK 217F) is greater than 3.5Mhours.

All models are packaged in a miniature, 7-pin SIP case that requires very little board space. The pin-out is industry standard & all case materials meet UL94-V0 requirements. They are specified for operation over the wide operating temperature range of -40°C to +105°C with no heat sinking required. Cooling is by free-air convection.

The IG275E are specifically designed for use in the driver circuits for IGBT devices such as the inverters used in solar power systems and railway traction systems.
