Help identifying two 8-pin SMD ICs

Sohaib@@

I'm working on a hardware board and I'm trying to identify two 8-pin SMD ICs. One has the marking code 1AEBK and the other has 1AELK (both look to be in an 8-pin TSOT-23 or similar package).Based on my board tracing and measurements:The 1AELK IC is acting as a synchronous step-down (buck) converter (maybe) It takes a 12V input rail and drives a 4R7 power inductor.The second IC right next to it is marked TAEBK.

What I need help with:Can anyone confirm the exact datasheet / manufacturer for these specific part codes (1AEBK and 1AELK)?

Are these standard MPS parts (like the MP2314 or a similar family), or could they be a different power management / load switch IC?

Any guidance, datasheet links, or pinout cross-references would be greatly appreciated. Thanks

!

    Good Morrow.

    Well the Google AI actually appears to have come up with a sensible answer! (who knew?!)

    |AELK, where the leading "1" or vertical bar is a pin-1/alignment marker) is the MP2314GJ (or automotive-grade MPQ2314GJ). Manufactured by Monolithic Power Systems (MPS), it is a high-efficiency synchronous step-down (buck) DC-DC converter in an 8-pin TSOT23-8 package.

    Seems to be what you are looking for - too easy! (Please no challenges I'm out of the industry , , , well for a while: we'll see!)

    Just a point - pics are best, there seem to be an infinite number of ways to mark SMT I.C.s (etc.) especially if they are fakes - when TI took over Burr-~Brown, THAT was fun! Mind you I did end up on TI's Expert Advisory Panel and got them to put the package codes on page 1 of each spec sheet when re-editted or updated!
