Infineon has added to its CoolMOS family to support the electro-mobility market.

These silicon-based, ICs can be used in both the PFC and the DC-DC stage of on-board charger systems and HV-LV DC-DC converters specifically optimized for electric-vehicle applications.

The CoolMOS CFD7A is fully compatible with system voltages up to 475 V DC.

Higher efficiency levels are made possible by the Kelvin-source concept reaching peak efficiency levels up to 98.4 percent measured.

Thanks to their intrinsic fast body diode and the broad portfolio line-up in TO and SMD packages, the CFD7A devices are  well-suited for PFC and DC-DC stages.

The product family allows reaching higher switching frequencies with low gate losses enabling more power-dense hence more compact designs.

CoolMOS  was targeted at the  automotive environment, especially in terms of cosmic radiation and design robustness. Cosmic radiation was tackled right from the beginning of the development process and is proven by experimental results.

The broad package portfolio enables easy design-in and additional benefits. When using Infineon’s 650 V CoolMOS CFD7A technology in combination with the D²PAK 7-pin package, customers benefit not only from the enhanced efficiency but the excellent thermal behavior and the extended creepage distances too.

The CoolMOS CFD7A family is manufactured on the highly automated 300 mm production line, which contributes to reach the zero-defect target in mass production while fulfilling the growing market demand.
