The 600V MDmesh M2 EP devices combine ST's strip layout with an improved vertical structure and an optimised diffusion process to approach the ideal switch, with low ON-resistance and the lowest available turn-off switching losses. They are tailored for very-high-frequency converters (f> 150 kHz), suiting them for demanding Power Supply Unit applications.
The devices are claimed to offer low switching losses, especially under light-load conditions. In addition to the Qg of down to 16nC exhibited by the MDmesh M2 devices, the M2 EP devices are said to feature up to a 20% reduction in Eoff, thus reducing the turn-off switching losses in hard-switching converters. This Eoff reduction in the low current range is said to boost efficiency under light-load conditions.
The enhanced shape of the turn-off waveforms is said to lead to higher efficiency and lower noise in resonant converters, allowing more energy to be stored and re-used, rather than dissipated as heat, cycle by cycle.
Offered in a range of packages the MDmesh M2 EP family targets power-supply applications that require the highest efficiency levels.
