Power Integrations' SIC1182K is a single channel gate driver in an eSOP-R16B package for SiC MOSFETs. Reinforced galvanic isolation is provided by Power Integrations’ revolutionary solid insulator FluxLink technology. The SIC1182K  boasts the highest peak-output gate current available without an external boost stage. Devices can be configured to support different gate-drive voltage requirements matching the range of requirements seen in SiC-MOSFETs today.

Key applications include UPS, photovoltaic systems, servo drives, welding inverters, and power supplies. The SIC1182K offers up to ±8A output drive current enables the product to drive devices with nominal currents of up to 600A (typical) without a booster stage. The device enables inverters with high system efficiency and allows the production of one design covering their entire portfolio of differently rated power inverters. A switching frequency of up to 150kHz supports multiple applications.
