LGS5145 is the closest found buck candidate for ME3116AM6G, pending pinout review.
ME3116AM6G is a 40V 1A SOT23-6 buck converter. Found alternatives need FAE review because pinout evidence is missing.
Frequency and FB data may differ.
Kept parts are SOT23-6.
No digital protocol shown.
PDF checks are pending.
No confirmed pin-compatible replacement is proven from the provided data.
Review LGS5145 first, then verify pinout, FB voltage, and external BOM.
Pinout and buck compensation are not verified.

LGS5145 is the closest found buck candidate for ME3116AM6G, pending pinout review.
| Feature / factor | ME3116AM6G | LGS5145 | DIO61845ST6 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SOT23-6 | SOT23-6 | SOT23-6 | SOT23-6 — same package; DIO61845ST6: same package | |
| Pinout | 6 pins | 6 pins | 6 pins | 6 pins — pin map absent; DIO61845ST6: pin map absent | |
| Voltage | 4.75-40V | 4.5-55V | 5-40V | 4.5-55V / 5-40V — VIN margin ok; DIO61845ST6: no 10% margin | |
| Current | 1A | 1A | 0.6A | 1A / 0.6A — same output rating; DIO61845ST6: load derating | |
| Application | 550kHz async buck | 1.2MHz async buck | sync buck | 1.2MHz async buck — BOM may change; DIO61845ST6: topology differs |
LGS5145 is the closest found candidate, but it still needs pinout and BOM review.
