Procurement Notes
Verify the specific package variant and temperature grade required for your application against the official datasheet. Confirm end-of-life status and longevity commitments directly with STMicroelectronics or authorized distributors, as availability may vary by region and production batch.
Selection Notes
Select this component when a unified solution for mixed linear and switching regulation is needed to reduce board space. Ensure input voltage ranges and thermal dissipation requirements align with the IC's specifications. Consider the integration level to simplify bill of materials compared to discrete regulator designs.
Part Context
The L9749 belongs to STMicroelectronics' portfolio of specialized power management integrated circuits. It is categorized under PMIC SPS ASICs, indicating its role in providing tailored power solutions rather than generic voltage regulation. This places it alongside other advanced power management devices designed for specific system-level integration needs.
Replacement Considerations
Consult STMicroelectronics documentation for direct pin-to-pin replacements or functional equivalents. Verify compatibility with existing PCB layouts and control interfaces before substituting with alternative PMICs from the same or different manufacturers.
