LP3907SQ-PFX6W/NOPB

Overview

The LP3907SQ-PFX6W/NOPB is a specialized power management integrated circuit (PMIC) manufactured by Texas Instruments. It integrates two synchronous buck converters and two low-dropout (LDO) regulators within a single package. The switching regulators provide output currents of 1A and 600mA, while the LDOs deliver 300mA each. The device operates with an input voltage range of 2.8V to 5.5V and features a 2.1MHz switching frequency. It utilizes an I2C interface for configuration and monitoring. The component is housed in a 24-WQFN package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates dual high-current synchronous buck converters and dual LDO regulators
• Features I2C interface for programmable control and status monitoring
• Supports advanced sequencing and power rail management functions

Applications

• Advanced application processors
• Field Programmable Gate Arrays (FPGA)
• Generic embedded systems requiring multi-rail power

Procurement Notes

Verify the specific suffix PFX6W against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the ordering part number matches the exact package variant required for the PCB footprint. Confirm RoHS compliance status through the official product data sheet before finalizing procurement orders.

Selection Notes

Select this component when a compact solution is needed for powering complex digital logic requiring multiple distinct voltage rails. The integrated nature reduces board space compared to discrete regulators. Consider the 2.1MHz frequency for smaller external passive components. Verify that the thermal performance of the WQFN-24 package meets the system's heat dissipation requirements under maximum load conditions.
