Hello all,

I can identify neither type nor manufacturer of above IC. Can anyone
help please?
Case is similar to 6 lead SOT / DDC / R-PDSO-G6 like:

Thank you very much in advance.

Find the maker of the logo for the chip fab and work backwards.

It looks like an A with a small i or r in it.

Thank you. This logo was hard to find, but meanwhile I found out that
it is from bcdsemi.com

So I found a base for my further investigations.

CONSTANT VOLTAGE AND CONSTANT CURRENT CONTROLLER AP4313
General Description

The AP4313 is a highly integrated solution for a constant
voltage/constant current mode SMPS application.
The AP4313 contains one 1.21V voltage reference
with ±1% accuracy, one current sensing circuit and two
operational amplifiers. Combining the voltage reference
with one operational amplifier makes AP4313 an
ideal voltage controller for use in adapters and battery
chargers. The other low voltage reference combined
with the other operational amplifier makes it an ideal
current limiter for output low side current sensing.

Well done James!

It has cost me hours to find out this information. Yesterday I could
only find a databook.rar file on the bcdsemi.com website. I had to
unpack it and had to look at one after the other datasheet...
BTW firstly I searched several websites with hundreds of logos. I have
then bought the SMD-Code databook online which again contained not my
SMD Code. But - in the appendix, the logo...

Thank you for your efforts and best regards

Karl

I started with Yahoo: "E6G site:bdcsemi.com" (note misspelled url),
zero results,
then "e6g sot23-6"
then "e6g RoHS"
then "e6g RoHS -star"

5 minutes total.

Yahoo "e6g sot-23-6 RoHS" works very well.

You bet.

Wow. I wish I had your search string logic.

Easy. I look for the most bizarre terms I'm sure will be in my

A good SMD reference you can download:
