Can someone identify a 5-Pin IC SMD with the marking code KV7RF? Searching in Google I didn't find anything. Any help on this?

2A picture worths thousand words. – Long Pham Apr 20 '19 at 18:50

2Please also add the dimensions of it – Huisman Apr 20 '19 at 19:13

@Huisman Dimensions are like SOT23-6 SMD – Maverick Apr 20 '19 at 21:48

@LongPham The SMD it too small to take a picture and I don't own an electronic microscope. – Maverick Apr 20 '19 at 21:49

@Maverick - FYI these are the current "Component Identification Question Guidelines". The more information you can supply from that list, the better the chances of identification. I understand the issue about a photo of the actual device (although holding a magnifying glass between camera and PCB can work), supplying PCB photos & description of the product can help to narrow down the type of device. Thanks. (Also see: "How do I identify SMD components? (or how do I identify any component)") – SamGibson Apr 20 '19 at 23:54

@LongPham Photo added. – Maverick Apr 21 '19 at 10:11

@Maverick Thanks for your effort :) It looks like a switching regulator IC to me. – Long Pham Apr 21 '19 at 10:24

@LongPham I am curious why this part is not documented! How it is supposed to test it if it's faulty? – Maverick Apr 21 '19 at 10:43

I count 6 pads, but think I only see 5 pins. Did pin 5 of the IC break off? – Huisman Apr 21 '19 at 22:03

@Huisman No, it did not break off. There are two of them on the PCB with on pin off by default. I got some answers from eevblog and they recognize it as a "DC regulator IC" as LongPham mention above like this https://datasheet.lcsc.com/szlcsc/SY8089AAAC_C78988.pdf – Maverick Apr 22 '19 at 10:46

Nice you have found the chip. Please note that when you call this a 6-Pin IC SMD while it has 5 pins, it is confusing. – Huisman Apr 22 '19 at 17:54

@Huisman thanx I fixed the misled 6-Pin description – Maverick Apr 23 '19 at 06:44

2Good. You found it. Make an answer with that information in it. Accept the answer. That finishes things up nice and neat. – JRE Apr 23 '19 at 07:30
