The latest results of the power module games are here and the winner of the Efficiency Testing Round was Analog Devices LTM4681Y !

DC-DC voltage converters are not capable of achieving 100% efficiency, as they inevitably generate losses, particularly in the form of heat, during the process of voltage regulation. In order to mitigate these losses, manufacturers employ MOSFETs, which help minimize switching losses, conduction losses, and reverse recovery losses. Additionally, manufacturers optimize the design of the inductor to reduce both DC and AC losses.

Power modules with higher efficiency tend to run cooler compared to those with lower efficiency.

In the efficiency round of the power module games, we found that Analog Devices LTM4681Y on test board DC2924A-A output channel 1 was the most efficient over an output load of 1-30A.

Predict a champion for your chance to win a Loadslammer.

This summer, ProGrAnalog are hosting our very own tournament – “The Power Module Games”.

Five DC-DC power module evaluation boards from MPS, Infineon, Analog Devices, Max Linear and Texas Instruments will be competing the chance to be crowned champion of the power modules!

We’re inviting the engineering community to join in with our competition and predict who will be crowned the ultimate champion. All entries that correctly predict the winner will enter a draw to win one of our LoadSlammer Pro Mini 40 test units.

How it works

We will be using ProGrAnalog’s LoadSlammer tools to evaluate the performance of these five competitors across 6 rounds of testing:

1. Transient Testing
2. 3D Sweep
3. Efficiency
4. Output Ripple
5. Current Density
6. Impedance
