DESCRIPTION
The PowerMESH
generation of MESH OVERLAY
™II is the evolution of the first
™. The layout re-
finements introduced greatly improve the Ron*area
figure of merit while keeping the device at the lea ding edge for what concerns swithing speed, gate
charge and ruggedness.
APPLICATIONS
■ HIGH CURRENT, HIGH SPEED SWITCHING
■ SWITH MODE POWER SUPPLI ES ( SMPS)
■ DC-AC CONVERTERS FOR WELDING
