L6711TR

DC DC Switching Controllers Overview

The L6711TR is a three-phase synchronous buck DC-DC switching controller manufactured by STMicroelectronics. It operates with a fixed switching frequency of 150kHz and supports a maximum duty cycle of 80%. The device features a positive output configuration and includes integrated soft-start, enable, frequency control, and phase control capabilities. It is designed for operation within a supply voltage range of 7.5V to 15V and functions reliably across a junction temperature range of 0°C to 125°C.

DC DC Switching Controllers Feature Summary

• Three-phase synchronous buck topology for high-current applications

DC DC Switching Controllers Procurement Notes

Verify component status as the L6711TR is listed as discontinued by the manufacturer. Confirm availability through authorized distributors or secondary market sources. Ensure compatibility with existing design specifications before procurement. Check for RoHS3 compliance and moisture sensitivity level requirements during handling and storage procedures.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring three-phase synchronous buck conversion with precise phase alignment. Consider the 150kHz switching frequency for balancing efficiency and component size. Evaluate thermal performance given the 48-TQFP package and operating temperature range. Verify that the 7.5V to 15V supply range matches the system's available rail.

DC DC Switching Controllers Part Context

The L6711 belongs to STMicroelectronics' portfolio of power management ICs focused on DC-DC switching controllers. It is part of the broader L6711 family, which provides multi-phase solutions for demanding power applications. The TR suffix indicates tape and reel packaging for automated assembly processes.

DC DC Switching Controllers Replacement Considerations

As the L6711TR is discontinued, evaluate alternative multi-phase buck controllers from STMicroelectronics or other manufacturers. Ensure replacement parts match the 48-TQEP package footprint and electrical characteristics. Verify compatibility with existing PCB layout and control algorithms.
