Supporting the needs of the electro-mobility market, Infineon Technologies launches its new product family: the CoolMOS CFD7A series. These silicon-based, high-performance products can be used in both the PFC (power factor correction) 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 d.c. Higher efficiency levels are made possible by the Kelvin-source concept, reaching peak efficiency levels up to 98,4%. Thanks to their intrinsic fast body diode and the broad portfolio lineup in TO and SMD packages, the CFD7A devices are very well suited for PFC and DC-DC stages.
The product family allows reaching higher switching frequencies with low gate losses, enabling more power-dense and therefore more compact designs. Additionally, the new CoolMOS technology platform was tailored to meet the needs of the rough 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 behaviour and the extended creepage distances too.
