Compared with OptiMOS 5, the company is claiming:
- Rds(on) better by 18%
- Qg x Rds(on) better by 29%
- Qgd x Rds(on) better by 42%
“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.
