TDA21240

概要

Highest efficiency on smallest form factor

DrMOS 4.0 x 4.0 x 1.0 mm³ offers best-in-class efficiency and very low power loss. Infineon can deliver these benefits by combining its latest generation 25V OptiMOS™ 5 MOSFET technologies with its proven MOSFET driver silicon. A significant reduction of switching losses enables superior efficiency at higher switching frequencies. Higher switching frequency operation, combined with an extremely small package, enables system designers to save board space and still deliver superior performance.
