AC-DC designers face the challenge of improving system efficiency and power density whilst at the same time reducing system costs. Infineon’s OptiMOS™ 5 40V and 60V families feature 15% lower R
(on) and 31% lower Figure of Merit (R
(on) x Q
g) compared to alternative devices thus are the perfect answer to these challenges.
These products are optimized for synchronous rectification in switched mode power supplies (SMPS) as well as a broad range of industrial applications such as motor control, solar micro inverters and fast switching DC-DC converters.
In addition with the new generation of 40V and 60V devices higher switching frequencies are now enabled which result in even higher power density. A monolithic integrated Schottky-like diode in the 40V SuperSO8 package (5mm x 6mm) leads to higher efficiency and a drastic reduction of the voltage overshoot. This in turn reduces the need for a snubber circuit and saves engineering effort and cost.
