TDA21310 Product Details


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.


 Compatible to Intel®VR12 Driver and Mosfets Module (DrMOS) functionality for Desktop/Server Applications
 For synchronous buck converter step down voltage applications
 Power MOSFETs rated 25 V for safe operation under all conditions
 Fast switching technology for improved performance at high switching frequencies (> 1 MHz)
 +5 V high side and low side MOSFETs driving voltage
 Compatible to standard +3.3 V PWM controller integrated circuits
 Small package: LG-UIQFN-32-2 (5 x 5 x 0.6 mm³)
 Optimized footprint for improved cooling by the PCB
 DC output current up to 40A
 94% peak efficiency at 1.2V1
 DC input voltage up to +16 V
 Remote driver disable function
 Includes bootstrap diode
 Undervoltage lockout
 Shoot through protection
 Tri-state PWM input functionality
 Top side cooling
 RoHS compliant


 Desktop and Server buck-converter
 Single Phase and Multiphase POL
 CPU/GPU Regulation in Desktop Graphics Cards, DDR Memory, Graphic Memory
 High Power Density Voltage Regulator Modules (VRM).
