LP3907QTL-VXSS

Overview

The LP3907QTL-VXSS/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 and supports switching frequencies up to 2.1MHz. The device provides outputs including 1A at 1.8V, 600mA at 3.3V, and 300mA at 2.8V. Packaged in a 25-uSMD (WFBGA) format, it functions within -40°C to 125°C and holds AEC-Q100 automotive qualification.

Feature Summary

Integrates dual high-current step-down DC/DC converters and dual linear regulators for efficient power distribution.
Features synchronous rectification technology to maximize conversion efficiency across varying load conditions.
Includes integrated sequencing logic to manage the startup and shutdown order of multiple power rails.

Applications

Advanced application processors requiring multi-rail power management
Field Programmable Gate Arrays (FPGAs)
Automotive infotainment systems

Procurement Notes

Verify the complete part number includes the /NOPB suffix to ensure compliance with RoHS standards. Confirm the specific thermal pad configuration matches the target PCB layout. Ensure the 25-WFBGA footprint aligns with existing assembly capabilities. Validate that the operating temperature range meets the environmental requirements of the final system design.

Selection Notes

Select this component when a compact solution is required for powering complex digital loads. The integrated sequencer simplifies board design by managing rail dependencies automatically. Consider the 2.1MHz switching frequency for optimizing external passive component size while maintaining stable output regulation under dynamic load steps.

Part Context

This device belongs to the LP3907 family of specialized power management ICs designed for portable and automotive electronics. It consolidates multiple power stages into a single package to reduce overall system footprint. The series is characterized by high integration levels and support for I2C interface control for dynamic adjustment.
