LP3907SQX-PFX6W/NOPB

Overview

The LP3907SQX-PFX6W/NOPB is a highly integrated power management IC (PMIC) from Texas Instruments. It features two high-current synchronous step-down DC-DC converters and two low-dropout linear regulators (LDOs). The buck converters operate at a typical switching frequency of 2100 kHz, with a maximum of 2600 kHz. The device supports I2C interface for configuration. It is housed in a 24-WQFN package with an exposed pad, suitable for space-constrained applications requiring multiple regulated voltage rails.

Feature Summary

• Integrates dual high-current synchronous buck converters and dual LDOs in a single package
• Supports I2C interface for programmable control and monitoring
• Features high switching frequency to minimize external component size

Applications

• Portable electronic devices requiring multiple voltage rails
• Industrial equipment with space-constrained power designs
• Communication systems needing efficient power management

Procurement Notes

Verify the exact suffix 'PFX6W' against the manufacturer's current datasheet to ensure pinout and electrical specifications match your design requirements. Confirm RoHS compliance status as per the latest environmental declarations. Check for any recent product change notices that may affect long-term availability or material composition.

Selection Notes

Select this component when a compact solution combining both switching and linear regulation is required. Ensure the input voltage range and output current capabilities meet the system load demands. Consider the thermal performance of the 24-WQFN package under maximum load conditions.

Part Context

This part belongs to the LP3907 family of PMICs from Texas Instruments. It is designed to replace discrete regulator solutions, reducing board space and assembly complexity. The SQ designation typically indicates automotive-grade qualification, aligning with AEC-Q100 standards for reliability in harsh environments.

Replacement Considerations

Check for direct substitutes like LP3907SQ-PJXIX/NOPB, ensuring pin compatibility and electrical parameter equivalence. Verify if alternative packages or suffixes offer the same functionality with different thermal or packaging characteristics.
