2.4 Using the MLTLDO2EVM-037 PCB Beyond Its Design Ratings
2.4.1 EVM Operation Beyond 5 Adc
The MLTLDO2EVM-037 PCB was designed to withstand current loading up to 5 Adc from VIN to VOUT,
and back through the ground plane, of each board. If larger load currents are used, the user should review
the connector data sheets to confirm they can withstand the load current. By design the current density
will be the largest at the package pins of each linear regulator. As such, the linear regulator package pins
will experience elevated heat and current density when the load current is above 5 Adc.
2.4.2 EVM Operation Beyond 50 Vdc (KVU|5 Package) or 100 Vdc (DCY, DDA, and KVU|3 Packages)
If the end use of the MLTLDO2EVM-037 PCB will require larger voltages than it was designed for, it may
still be possible to use it if the proper precautions are taken. A common method to extending the voltage
rating of a PCB is to apply conformal coating. Conformal coatings are readily available through most
distributors.
