These silicon-based, high-performance products can be used in both the PFC and the DC-DC stage of on-board charger systems and HV-LV DC-DC converters specifically optimised for electric-vehicle applications.
The CoolMOS CFD7A is fully compatible with system voltages up to 475 V DC. Higher efficiency levels are 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 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, in addition the CoolMOS technology platform has been tailored to meet the needs of the rough automotive environment, especially in terms of cosmic radiation and design robustness..
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 will be able to benefit not only from the enhanced efficiency but the improved thermal behaviour 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.
