Distributor's Review & Application Insight

FAE Insight: When switching frequency and efficiency are paramount, the 2FSC0110 is the core to use. Its extremely low propagation delay and high Common-Mode Transient Immunity (CMTI) are essential for reliably driving SiC MOSFETs at hundreds of kilohertz. We see this core being designed into high-power-density applications like onboard EV chargers, server power supplies, and solar microinverters. It provides the core performance needed to truly take advantage of SiC technology.

Q: Why is high CMTI so important for SiC drivers?

A: SiC MOSFETs switch extremely fast, creating very high dv/dt (voltage change over time). This can induce noise across the isolation barrier, potentially corrupting the PWM signal and causing catastrophic failure. A driver with high CMTI, like the 2FSC0110, can withstand this noise and maintain stable operation.
