LP3907SQ-BFX6W/NOPB

Overview

The LP3907SQ-BFX6W/NOPB is a specialized Power Management IC (PMIC) from the LP3907 series, manufactured by Texas Instruments. It integrates two synchronous buck converters and two Low Dropout (LDO) regulators within a single package. The device features a switching frequency of 2.1 MHz and supports an input voltage range of 2.8 V to 5.5 V. It operates within an ambient temperature range of -40°C to +85°C and utilizes a 24-WQFN (4x4 mm) package with exposed pad for thermal management.

Feature Summary

• Integrates dual high-current synchronous buck converters and dual low-noise LDOs in a compact footprint
• Features I2C interface for programmable output voltage control and dynamic power management
• Includes integrated sequencing and monitoring functions for system reliability

Applications

• Advanced application processors
• Field Programmable Gate Arrays (FPGA)
• Portable electronic devices requiring multi-rail power supplies

Procurement Notes

Verify the exact suffix against the manufacturer's official datasheet to confirm pinout and electrical specifications. Ensure the component meets AEC-Q100 automotive qualification requirements if used in automotive environments. Cross-reference the specific tape-and-reel packaging details with authorized distributors to match assembly line requirements.

Selection Notes

Select this component when a single IC solution is required to power multiple rails for complex digital logic. It is suitable for designs needing both high-efficiency switching regulation for core voltages and low-noise linear regulation for sensitive analog or RF sections. Consider the 24-pin WQFN package constraints for PCB layout and thermal dissipation capabilities.

Part Context

This part belongs to the LP3907 family of PMICs designed for portable applications. It consolidates multiple power stages into one chip to reduce board space and component count. The LP3907 series is widely used in mobile phones, tablets, and other handheld devices where power efficiency and size are critical design parameters.

Replacement Considerations

Check for LP3907SQ-PJXIX/NOPB or LP3907SQ-JXQX/NOPB as potential functional equivalents within the same family, ensuring package compatibility and pin alignment before substitution.
