Infineon Opti5

by Susan Nordyk @ edn.com:

Extending Infineon Technologies’ OptiMOS 5 portfolio of power MOSFETs are 80-V and 100-V variants optimized for high switching frequencies used in synchronous rectification applications for telecom and server power supplies, as well as industrial applications such as solar, low-voltage drives, and power adapters. OptiMOS 5 devices slash on-resistance by up to 45% for 80-V parts and up to 24% for 100-V parts compared to the previous generation.

Additionally, the OptiMOS 5 80-V variant offers a 38% reduction in output charge and the 100-V variant a 25% reduction. Less output charge means reduced switching losses and lower voltage overshoot in hard switching topologies and synchronous rectification. Moreover, a reduction in gate charge of 24% for 80-V devices and 29% for 100-V devices also reduces switching losses, especially at light load operation and in applications requiring high efficiency throughout the entire load range.
