LP3907QSQX-JXI7/NOPB

Overview

The LP3907QSQX-JXI7/NOPB is a specialized power management IC (PMIC) from Texas Instruments, designed for automotive applications. It integrates four output regulators: two synchronous buck converters and two low-dropout (LDO) linear regulators. The device operates within an input voltage range of 2.8V to 5.5V and supports switching frequencies up to 2.1MHz. It features integrated sequencing and is housed in a 24-WQFN package with exposed pad, suitable for space-constrained designs.

Feature Summary

• Integrates dual synchronous buck converters and dual LDOs for comprehensive power rail generation.
• Includes built-in sequencing logic to manage startup and shutdown transitions of multiple outputs.
• Qualified for automotive environments under AEC-Q100 standards with extended temperature capabilities.

Applications

• Advanced application processors requiring multiple regulated voltage rails.
• Field-Programmable Gate Array (FPGA) power supply systems.
• Automotive electronic control units (ECUs) needing reliable PMIC solutions.

Procurement Notes

Verify the specific suffix JXI7 against official Texas Instruments documentation to confirm pin compatibility and electrical characteristics. Ensure the component meets AEC-Q100 grade requirements for your target automotive environment. Cross-reference the datasheet revision date to validate current manufacturing status and any potential design changes.

Selection Notes

Select this component when a single-chip solution for quad-output regulation is required in automotive contexts. Compare its integrated sequencing features against discrete regulator setups to reduce board space. Evaluate the thermal performance of the 24-WQFN package relative to your system's heat dissipation constraints and ambient operating conditions.

Part Context

This part belongs to the LP3907 family of multi-output PMICs. It shares functional similarities with variants like LP3907QSQ-JXIP/NOPB but may differ in packaging or specific electrical tolerances. The 'Q' designation indicates automotive qualification, while 'SQ' often denotes specific reliability grades or packaging variations within the TI portfolio.

Replacement Considerations

LP3907QSQ-JXIP/NOPB is listed as a parameter-equivalent alternative. Verify pin-to-pin compatibility and exact output voltage/current specifications before substitution. Consult the latest TI datasheets to ensure no functional differences exist between the JXI7 and JXIP suffixes regarding internal circuitry or thermal performance.
