Infineon Technologies 2EDF9275F & 2EDS9265H EiceDRIVER™ ICs

The two new family members of the 2EDi family are designed for the use in high-performance power conversion applications. Very strong 4 A /8 A source/sink dual-channel gate drivers increase efficiency in CoolSiC™ MOSFET half-bridges. The low propagation delay of 37 ns, combined with highly accurate and stable timing over temperature and production, enables further efficiency gains within and across galvanically isolated power stages or in multi-phase/multi-level topologies.
