XDL FOR AUTOMOTIVE

World’s Smallest AEC-Q100 Qualified Buck DC/DC Solutions

DC/DC + Coil Integration for Automotive

Torex’s XDL Family provides integrated coil step-down DC/DC solutions that offer high levels of performance and reliability for the demanding and space constrained automotive applications. XDL products support a wide input voltage range of up to 36V (46V surge), provide superior thermal performance and minimised radiated noise (EMI). XDL packages also have wettable flanks.

 

 

Optimised for Space Constrained Applications

Ideal for space constrained applications such as sensors and cameras, small control modules, telematics, infotainment & HMI.

 

 

 

Low Radiated Noise

Below we compare the near magnetic field radiation generated by the XDL Series Micro DC/DC against the performance of our external coil DC/DC.

Test conditions: VIN=5.0V, VOUT=3.3V, IOUT=300mA

 

High Reliability Package

XDL package structure comes with wettable flanks that can achieve 100% Automated Visual Inspection (AVI) success rate and lowers the inspection time. Furthermore, the package heat dissipation is enhanced with the use of large DC/DC thermal pad that contributes to high levels of reliability.
