General Description

The Infineon TDA21211 is a multichip module that incorporates Infineon’s premier MOSFET technology for a single high

side and a single low side MOSFET coupled with a robust, high performance, high switching frequency gate driver in a

single 40 pin QFN package. The optimized gate timing allows for significant light load efficiency improvements over

discrete solutions. State of the art MOSFET technology provides exceptional full load performance. Thus this device has

a clear advantage over exisiting approaches in the marketplace when both full load and light load efficiencies are

important.

The Driver+MOSFET IC TDA21211 (DrMOS) is pin to pin compatible and compliant with the Intel 6x6 DrMOS

specification. The device package height is only 0.8mm, and is an excellent choice for applications with critical height

limitations.
