Infineon IGI60F2020A1LAUMA1

IGI60F2020A1L combines a half-bridge power stage consisting of two 200 mΩ (typ. Rdson) / 600 V enhancement - mode CoolGaN HEMTs with dedicated gate drivers in a small 8 x 8 mm QFN - 28 package. In the low - to - medium power area it is thus ideally suited to support the design of high - density AC/DC chargers and adapters utilizing the superior switching behavior of CoolGaN HEMTs. CoolGaN and related power switches provide a very robust gate structure. When driven by a continuous gate current of a few mA in the “on” state, a minimum on - resistance Rdson is always guaranteed. Due to the GaN - specific low threshold voltage and the fast switching transients, a negative gate drive voltage is required in certain applications to both enable fast turn - off and avoid cross - conduction effects. This can be achieved by the well - known RC interface between driver and switch. A few external SMD resistors and caps enable easy adaptation to different power topologies. The driver utilizes on - chip coreless transformer technology (CT) to achieve signal level - shifting to the high - side. Further, CT guarantees robustness even for extremely fast switching transients above 300 V/ns.
