LP3907SQX-JXQX/NOPB

Overview

The LP3907SQX-JXQX/NOPB is a specialized power management IC from Texas Instruments, featuring two synchronous buck converters and two low-dropout linear regulators. It operates within an input voltage range of 2.8V to 5.5V and supports switching frequencies up to 2.1MHz. The device integrates an I2C interface for configuration and monitoring. It is housed in a 24-WQFN package with dimensions of 4x4 mm and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates dual high-current synchronous buck converters and dual LDOs in a single compact package.
• Features an I2C serial interface for programmable control and system monitoring.
• Includes integrated soft-start functionality to manage inrush current during startup.
• Supports independent enable controls for each regulator output.

Applications

• Advanced application processors
• Field Programmable Gate Arrays (FPGA)
• Generic portable electronic devices

Procurement Notes

Verify the specific suffix JXQX against official datasheets to confirm pinout and thermal pad configurations. Ensure compatibility with AEC-Q100 automotive qualification requirements if applicable. Confirm that the 24-WQFN footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a combined solution for digital core voltages and analog rails is required. The I2C interface allows for dynamic voltage scaling, making it suitable for power-sensitive applications. Consider the 24-WQFN package size relative to available board space and thermal dissipation needs.

Part Context
