Please help me identify an 8-pin IC marked ( YS17 RBSCK0 2022QED ), i have a LED circuit in which this IC is burned out. Can anyone tell me the alternative of this IC. I searched the net but I couldn't find the part anywhere. On this IC in the PCB where the negative and positive in-out points were coming. I have drawn them in the picture below
It's a Padauk (应广科技) MCU, possibly a PMS150C-S08. In this thread on the eevblog the poster asks if a SOP-8 IC with the marking
YS17
RBCWA5
1851XCD
is a genuine PMS150C and later gets the confirmation from Padauk. However, on lcsc.com the markings look completely different, so it's unclear to me if the markings really contain a product code or if they are just a lot number/date code. You will have to ask Padauk to confirm.
Other Padauk parts have similar markings, so I think it's clearly the correct manufacturer. Here a PMS152-S08 as example:
