Infineon is aiming at high switching frequency applications dc-dc converter applications such as telecom and solar with its OptiMOS 6 family of 100V mosfets.
Compared with OptiMOS 5, the company is claiming:
“In a 600W, 36-60V to 12V zero-voltage switched buck-boost converter, OptiMOS 6 in SuperSO8 with 2.2mΩ can achieve 1% higher efficiency than the 2.7mΩ BSC027N10NS5 OptiMOS 5 across the whole load range,” claimed Infineon. “This results in a 7W lower power loss due to improved charges and Rds(on), enabling up to 15% higher power density.”
Applications are foreseen in switch mode power supplies, as well as solar, power tools, drones and battery management systems.
Parts are available now in 5 x 6mm SuperSO8 and 3.3 x 3.3mm PQFN 3.3×3.3.
Total gate charge for the 2.24mΩ ISC022N10NM6 is 73nC typ (91nC max) at 50Vdd 25A Id 0-10Vgs. Typical diode reverse recovery charge is 70nC at 50Vr, 25A If, 100A/µs dif/dt (325nC at 1,000A/µs). Its data sheet is here
