Description
The Infineon TDA21310 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 32 pin LG-UIQFN-32-2 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 Infineon’s family of digital multi-phase controllers, the TDA21310 forms a complete corevoltage regulator solution for advanced micro and graphics processors as well as point-of-load applications. The TDA21310 is not pin compatible to the Intel 6x6 DrMOS specification, but compatible by functionality. The device package height is only 0.6 mm, and is an excellent choice for applications with critical height limitations. It has reduced thermal impedance from junction to top case compared to DrMOS, allowing for top side cooling.
