Hi guys
I am having troubles of managing the heat (too hot to touch) from my DC/DC converter. So I would like to improve the efficiency of my DC/DC converter. I think I have narrowed it down to either my PCB layout, or my inductor selection, but I am not sure.
Current efficiency is about 80%, generating about 2.6w of heat @ 5.3V 2A load, 12VIN. I am hoping to improve the efficiency to about 90%.
So I thought I can post it here and ask for any idea.
I am suing this DC/DC converter ACT4533BYH-T and this inductor, I am using low ESR input and output cap.
Here is the circuit (straight out of the datasheet, with minor modification)
Here is the pcb:
