Strong parametric match on voltage, current, and frequency in the same SOT23-6 package.
TMI3252 is a 2A, 18V synchronous buck converter in a SOT23-6 package. Finding a replacement involves matching input voltage, output current, switching frequency, and pinout.
All viable candidates are in the same SOT23-6 package.
Switching frequency and temperature range vary between candidates.
These are analog ICs with no firmware.
Direct replacement for TMI3252 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
ETA8120S2G appears to be the strongest candidate, matching key electricals and package, but requires pinout and temperature verification.
The main risks are pinout incompatibility and differences in switching frequency, which impacts external component values and EMI performance.
