Product details

Overview

LP3907SQ-PJXIX/NOPB from Texas Instruments is a multi-output PMIC integrating dual buck converters and dual LDO regulators for advanced application processors and FPGA-oriented portable systems. The device provides a 1A buck rail, a 600mA buck rail, and two 300mA LDO rails from a compact WQFN package.

As part of the TI LP3907 product family, LP3907SQ-PJXIX/NOPB combines 2.8V to 5.5V input operation, an I2C-compatible serial interface, independent control of device functions, precision reference behavior, and configurable output options. For engineers reviewing the LP3907SQ-PJXIX/NOPB datasheet, LP3907SQ-PJXIX/NOPB pinout, LP3907SQ-PJXIX/NOPB application, or LP3907SQ-PJXIX/NOPB equivalent, this device is widely used in application processor rails, FPGA supplies, portable multimedia systems, handheld electronics, battery-powered modules, and compact multi-rail embedded architectures.

Technical Context

In portable processor systems, LP3907SQ-PJXIX/NOPB operates as a four-output PMIC. The two buck regulators provide efficient high-current rails, while the two 300mA LDO regulators supply internal processor functions, I/O rails, or lower-noise auxiliary loads.

The I2C-compatible serial interface allows independent control of device functions and settings, making the PMIC useful where processors need rail control, power-state transitions, or configurable startup behavior.

LP3907SQ-PJXIX/NOPB is commonly used where a 2.8V to 5.5V battery or system input must generate several coordinated rails in a 24-pin WQFN footprint without separate regulator ICs.

Pinout & Package

The LP3907SQ-PJXIX/NOPB pinout includes buck input and switch pins, LDO outputs, I2C control pins, enable and power-good functions, feedback/sense connections, and thermal ground pins.

For PCB design, each buck converter should have compact inductor and capacitor placement, I2C lines should be routed away from switching nodes, and LDO output capacitors should be placed close to the PMIC.

Equivalent & Alternatives

When evaluating a LP3907SQ-PJXIX/NOPB equivalent, engineers should compare buck current, LDO current, I2C control, OTP configuration, package, sequencing, dynamic voltage scaling, and automotive qualification needs.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LP873347RHDT	Same LP8733 configuration family with a different packing or orderable suffix.	Used when the same configured PMIC is needed in another packing option.	Compare exact orderable suffix, package, reel/tray format, and availability.
TPS65023	Texas Instruments multi-output PMIC with several DC-DC and LDO rails but different configuration and control behavior.	Used in embedded processor platforms requiring multi-rail power management.	Compare rail count, current ratings, I2C features, package, and default voltage settings.

Compared with LP873347RHDT, LP3907SQ-PJXIX/NOPB should be selected when its exact orderable suffix and configuration match the board requirement. LP3907SQ-PJXIX/NOPB vs TPS65023 selection depends on rail current, I2C control needs, OTP defaults, package, and processor power-tree architecture.

Quality

LP3907SQ-PJXIX/NOPB should be sourced as original Texas Instruments components through traceable supply channels. Quality checks may include VQFN inspection, top-mark validation, solderability testing, and verification of buck, LDO, and I2C functions.

Production validation should include rail sequencing, I2C configuration, output voltage accuracy, dynamic voltage scaling, load-transient response, LDO stability, thermal behavior, and startup timing.

Availability

LP3907SQ-PJXIX/NOPB available at Aetrix Electronics and is suitable for automotive, industrial, camera, infotainment, and processor-based embedded systems requiring configurable multi-rail PMIC supply support.

Supply support may include volume procurement planning, scheduled delivery arrangements, traceable sourcing management, and long-term supply support for OEM, industrial electronics, automotive electronics, and embedded product programs. Sample and NPI supply support, as well as urgent in-stock supply support, can also be arranged for prototype builds, pilot runs, and time-critical production needs.

For production builds, confirming OTP configuration, orderable suffix, package, rail-current budget, software interface, lifecycle status, and sourcing continuity helps reduce procurement risk.
