Best Alternatives to TMI3252

Package: SOT23-6MIPMIC - Voltage Regulators - DC DC Switching RegulatorsOutput Current: 2 AInput Voltage Range: 4.5 V to 18 VSwitching Frequency: 600 kHzOutput Voltage: 0.8 V (Adjustable)Topology: Buck (Step-Down)

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.

AI replacement insight

Package risklow

All viable candidates are in the same SOT23-6 package.

Electrical riskmedium

Switching frequency and temperature range vary between candidates.

Firmware risklow

These are analog ICs with no firmware.

Can it be replaced directly?

Direct replacement for TMI3252 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

ETA8120S2G appears to be the strongest candidate, matching key electricals and package, but requires pinout and temperature verification.

Main risk

The main risks are pinout incompatibility and differences in switching frequency, which impacts external component values and EMI performance.
