DESCRIPTION
The PowerMESH™II is the evolution of the first generation of MESH OVERLAY™. The layout refinements 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-EFFICIENCY DC-DC CONVERTERS
■ UPS AND MOTOR CONTROL
