LP3907SQX-TJXIP/NOPB

Overview

The LP3907SQX-TJXIP/NOPB is a Texas Instruments PMIC featuring two synchronous buck converters and two LDOs. It operates with an input voltage range of 2.8V to 5.5V. The switching frequency is fixed at 2.1MHz. Output 1 provides up to 1A, while Output 2 supports up to 600mA. Outputs 3 and 4 are LDOs rated for 300mA each. The device includes an I2C interface for configuration. It is housed in a 24-WQFN package and functions within a temperature range of -40°C to 125°C.

Feature Summary

• Integrates dual high-current synchronous buck converters and dual low-dropout regulators.
• Features an I2C serial interface for programmable control and monitoring.
• Includes integrated sequencer and power good indicators for system management.

Applications

• Advanced application processors
• Field-programmable gate arrays (FPGAs)
• Portable electronic devices

Procurement Notes

Verify the specific suffix TJXIP against official datasheets to confirm tape and reel packaging specifications. Ensure compatibility with AEC-Q100 automotive qualification requirements if applicable. Cross-reference the full part number with manufacturer databases to avoid ordering errors due to similar suffixes.

Selection Notes

Select this component when a compact solution combining switching regulators and LDOs is required. Consider the 2.1MHz switching frequency for smaller passive components. Evaluate the I2C interface needs for dynamic voltage scaling. Verify thermal performance within the 24-WQFN package constraints for the intended load currents.

Part Context

This part belongs to the LP3907 series of multi-output power management ICs from Texas Instruments. It is designed for space-constrained applications requiring multiple regulated rails. The SQ designation indicates automotive grade qualification. The device consolidates power supply functions into a single small footprint.
