LP3907QSQX-JJXP/NOPB

Overview

The LP3907QSQX-JJXP/NOPB is an automotive-grade PMIC from the LP3907 series, manufactured by Texas Instruments. It integrates four output regulators: two synchronous buck converters and two low-dropout (LDO) linear regulators. The device operates within a supply voltage range of 2.8V to 5.5V and supports a switching frequency of 2.1MHz. It features I2C interface control for programmable outputs and includes built-in sequencing capabilities. The component is housed in a compact 24-WQFN package and is qualified to AEC-Q100 standards for automotive applications.

Feature Summary

• Integrates dual high-current synchronous buck converters and dual LDOs for efficient multi-rail power generation.
• Features I2C digital interface for precise configuration and monitoring of regulator parameters.
• Includes internal sequencing logic to manage power-up and power-down transitions safely.
• Qualified for automotive environments with extended temperature ratings and robust reliability.

Applications

• Advanced application processors requiring multiple regulated voltage rails.
• Field-Programmable Gate Array (FPGA) core and I/O power distribution.
• Automotive infotainment systems and telematics units.

Procurement Notes

Verify the specific suffix JJXP against official Texas Instruments documentation to confirm pinout and electrical characteristics. Ensure the component meets AEC-Q100 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 IC solution is needed to replace multiple discrete regulators in space-constrained designs. Consider the 2.1MHz switching frequency for balancing efficiency and external component size. Verify that the integrated buck and LDO current capabilities meet the peak load demands of the processor or FPGA being powered.
