Practical thermal design with DC/DC power modules


All DC/DC converters dissipate power in the form of heat. This heat has to be managed properly so that the converter maintains operation within the recommended temperature limits. Usually, the copper on the printed circuit board (PCB) is utilised to help dissipate the heat.

Synchronous buck DC/DC controller with wide duty cycle range

The LM5146-Q1 100V synchronous buck controller from Texas Instruments regulates from a high input voltage source or from an input rail subject to high voltage transients, minimising the need for external surge suppression components.


Comparison of vibration energy harvesting devices

Battery replacement in portable electronics is laborious, so the search is on for more efficient power sources. Among the different energy sources under research, vibration sources seem to be the most suitable for small-scale power generation for low-power electronics. Harvesting energy by converting waste vibration energy into electrical energy is useful.
