I just burned one capacitor and regulatir- transistor on my beelink mini PC circuit board caused by my DIY power supply.
Any one can help identify this IC marled as “K6=8G R0E” ?
Beelink tech support refused to give me any information about this IC, so I m trying to fibg save my PC… Please check the photo. Akira

Wow, big thanks for yrs quick reply, I dunno how you find it but it looks quite close…

The capacity burned, it seems 10uf 25V 0805.
Top right resistance, I measured it, it was 12.5 ohm, I m not sure it’s on a good condition or damaged;(
For the capacitor, look at these options

Hi tangomaniaque,
That seems like a very low resistance. From the datasheet, it looks like that resistor is connected to the “Enable” pin, as seen in the drawing below. If so, and if one follows the “Typical Application Circuit”, then it ought to be much higher, such as 1K Ohm.
It looks like they recommend a pair of 10uF caps for Vin, but state that 10uF is the minimum recommended value.
That looks like a fairly catastrophic event on your board. Even if you replace those three parts, I wouldn’t be highly confident that it will fix all that ails it.
