Description
3.2 General Description
The Infineon TDA21321 is a multichip module that incorporates Infineon’s premier MOSFET technology into a
single high-side and a single low-side MOSFET. This is coupled with a robust, high performance, high switching
frequency gate driver on a single 38 pin LG-WIQFN-38-1 (6.6x4.5x0.6 mm³) package. The optimized gate timing
enables significant light load efficiency improvements over discrete solutions. State of the art MOSFET
technology provides exceptional performance at full and light load.
When combined with Infineon’s Primarion™ Controller Family of Digital Multi-phase Controllers, the TDA21321
forms a complete core-voltage regulator solution for advanced micro and graphics processors as well as point-
of-load applications. The device package height is 0.6 mm. It is an excellent choice for applications with critical
height limitations and has reduced thermal impedance from junction to top case compared to DrMOS, allowing
for top side cooling.
The power density for transmitted power of this approach is approximately 50 W within a 28 mm2 area.
