LX1671BCLQ-TR

DC DC Switching Controllers Overview

The LX1671BCLQ-TR is a highly integrated power supply controller IC manufactured by Microsemi Corporation. It features three PWM switching regulator stages and an additional onboard linear regulator, designed for complex power management applications. The device operates in a buck topology to provide positive output voltage regulation. It is housed in a 38-pin MLPQ package with dimensions of 5x7 mm, suitable for surface-mount assembly in space-constrained electronic designs requiring multi-rail power sequencing.

DC DC Switching Controllers Feature Summary

• Integrates three independent PWM switching regulator stages for multi-output power generation
• Includes an onboard linear regulator stage alongside the switching controllers
• Designed for positive output voltage regulation using buck topology

DC DC Switching Controllers Applications

• Complex power management systems requiring multiple regulated rails
• Space-constrained electronic designs utilizing surface-mount packaging

DC DC Switching Controllers Procurement Notes

Verify the specific manufacturer designation, as sourcing may involve Microsemi or its successor entities such as Microchip. Confirm that the component meets all required environmental and compliance standards for your specific application region. Ensure the package type matches the 38-MLPQ (5x7) specification during integration planning.

DC DC Switching Controllers Selection Notes

Select this component when a single IC solution is required to manage multiple power rails efficiently. The integration of both PWM and linear regulators reduces board space and component count. Consider the thermal requirements associated with the MLPQ package and the specific current demands of the three switching stages before finalizing the design.
