July 20, 2016 - MicroPower Direct introduced the IG120-20, a miniature DC/DC converter. It is designed to provide the asynchronous output voltage levels required to properly bias the gate drive of SiC semiconductors.
The IG120-20 operates from a 15 VDC input, providing dual outputs of +20V and -4 VDC; the recommended negative gate bias levels for most SiC driver circuits. Standard features include continuous short circuit protection, efficiency as high as 83%, and an input/output isolation level of 3,500 VAC (6,000 VDC). The IG120-20 is approved to EN 60950 and has an MTBF (perMIL HDBK 217F) of greater than 3.5 Mhours.
The IG120-20 is packaged in a miniature, 7-pin SIP case that requires little board space. The pin-out is industry standard and all case materials meet UL94-V0 requirements. It is 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 IG120-20 is specifically designed for use in the driver circuits for SiC MOSFET devices. It simplifies the task of setting up the correct gate bias levels while also providing a high level of isolation to the gate drive circuit.
