Hi all,
I am using MIC29300-5.0BU in my design. But I have a issue with temperature of MIC29300.
When I supply 12VDC to Vin and the load is very low (100mA). MIC29300 is very hot although I used PCB heat sink for TAB (package TO263) with size: 12x12mm.
But when I used Vin 6VDC. I haven't meet that. Temperature of MIC29300 is low.
In the my other board, I use MIC29302BU and Vin 12VDC but temperature is low.
I don't explain that.
Could you help me, please?
Thank,
