Original question:

TPS62130A: vs TPS62150A-Q1 vs TLV62130 vs TPS62140

TPS62140: Choice between TPS/TLV 62140 etc

Part Number: TPS62140
Other Parts Discussed in Thread: TLV62130, TLV62150

Hey team,

I'm doing a power project that requires a drop-down from 12V to 5V @ 1.8A, with BOM cost being a key careabout then size then efficiency. I notice on Webench that the both the TLV62140 and the TPS62140 are recommended, with the TPS62140 being markedly better with a smaller size and ~$0.30 less BOM cost than the TLV62130/62140 (not to mention slightly higher IC cost). I was curious why this is and if this is the case, in what circumstance would the TLV part be chosen over the TPS? This is purely for educational purposes, so please feel free to provide as much scrutiny/details as desired. I'll likely switch out my design for the TPS counterpart, as I just came across this and am wondering why I didn't pick this sooner!

Thanks in advance

    Hi Marco,

    On the TLV devices, there are only TLV62130 and TLV62150 but there is no TLV62140. Can you confirm what part numbers are you trying in WEBENCH? I can check out the tool with those two part numbers.

    Thanks,

    My apologies, it is the TLV62130.

    I tried the conditions in WEBENCH and found the same BOM footprint on both TLV and TPS counterparts. The TLV device is slightly lower in cost than the TPS device but the other BOM component choices or overall footprint should be identical. Both devices are p2p compatible so you can swap one for the other.

    Some differences are below:

    1. output voltage can be 6V(TPS) vs 5.5V(TLV),

    2. Lower quiescent current 17uA(TPS) vs 19uA(TLV)

    3. More tighter initial output voltage accuracy on the TPS - check Electrical characteristics table.

    Thanks,
