LP3907QSQ-JXIP/NOPB

Overview

The LP3907QSQ-JXIP/NOPB is an automotive-grade Power Management Integrated Circuit (PMIC) from Texas Instruments. It integrates four outputs: two synchronous buck converters rated at 1A and 600mA, and two Low Dropout (LDO) regulators rated at 300mA each. The device operates with a supply voltage range of 2.8V to 5.5V and features a switching frequency of 2.1MHz. It supports I2C interface control for programmability and includes built-in power sequencing. The component is housed in a compact 24-WQFN package measuring 4x4mm and is qualified under AEC-Q100 standards for operation between -40°C and 125°C.

Feature Summary

• Integrates dual synchronous buck converters and dual LDOs for comprehensive power management
• Features programmable power sequencing controlled via I2C interface
• Qualified for automotive applications under AEC-Q100 standards
• Supports dynamic voltage scaling for optimized efficiency

Applications

• Advanced application processors
• Field Programmable Gate Arrays (FPGA)
• Automotive infotainment systems

Procurement Notes

Verify the specific suffix JXIP against the official datasheet to confirm pinout and thermal pad configuration. Ensure the order matches the QSQ automotive grade designation rather than standard commercial variants. Confirm RoHS compliance status as per the latest manufacturer documentation before finalizing procurement.

Selection Notes

Select this component when designing for automotive environments requiring high integration and strict temperature resilience. The 24-WQFN package suits space-constrained layouts. Verify that the required output voltages align with the fixed internal settings or external resistor dividers specified in the electrical characteristics table.

Part Context

This part belongs to the LP3907 family of multi-output PMICs designed for low-power processing applications. The QSQ variant specifically denotes automotive qualification, distinguishing it from commercial counterparts like the LP3907SQ series. It consolidates multiple discrete regulator functions into a single footprint to reduce board complexity.

Replacement Considerations

LP3907QSQ-JXI7/NOPB is documented as a parameter-equivalent substitute within the same product family.
