LP8764-Q1
Four-buck configurable multiphase PMIC
Four buck cores can form a single four-phase rail or multiple outputs for processor power. Unlike TPS6594-Q1 it has no four-LDO block; verify exact-OPN NVM, interface and sequencing instead of assuming a drop-in replacement.

Key specifications
Orderable variants (OPNs)
The GPN is for selection; the full OPN is for ordering. These examples were observed on the verification date, not live stock. Variants may differ in package, temperature, gain/threshold and, for PMICs, NVM/sequencing. Distinguish TA from TJ in the exact datasheet.

Typical applications
FAQ
Why is it not a direct TPS6594-Q1 replacement?
Buck/LDO count, package, pins and default sequencing differ. Rebuild the rail map and verify monitoring and software initialization.
Does the OPN suffix only describe shipping packaging?
Not necessarily. PMIC variants can bind NVM configuration. Do not infer every field from packaging suffixes; use the corresponding configuration documentation.
How should I verify the LP8764-Q1 orderable?
The page lists 7 OPN examples from official material checked on 2026-11-06. Match package, function options and temperature definitions; obtain live price/stock from TI or authorized distributors.
