General Description
The Infineon TDA21220 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.
When combined with the Infineon’s family of digital multiphase controllers, the TDA21220 forms a complete
core-voltage regulator solution for advanced micro and graphics processors as well as point-of-load
applications.
The TDA21220 is pin to pin compatible and compliant with the Intel 6x6 DrMOS specification. The device
package height is only 0.8 mm, and is an excellent choice for applications with critical height limitations.
