L6726ATR

DC DC Switching Controllers Overview

The L6726ATR is a synchronous buck DC-DC switching controller manufactured by STMicroelectronics. It operates with a fixed switching frequency of 270 kHz and supports an adjustable duty cycle up to 80%. The device accepts a supply voltage range of 4.1V to 13.2V and provides a single positive output via a transistor driver stage capable of sourcing 1.5 A. It utilizes an 8-SOIC surface-mount package and functions within a junction temperature range of -40°C to 150°C.

DC DC Switching Controllers Feature Summary

• Synchronous rectification architecture for improved efficiency
• Integrated power good signal for system monitoring
• Supports phase control and frequency control features
• Operates in negative temperature environments down to -40°C

DC DC Switching Controllers Applications

• General-purpose step-down voltage regulation
• Embedded power management systems requiring synchronous control
• Industrial equipment operating in wide temperature ranges

DC DC Switching Controllers Procurement Notes

Verify component status as the L6726ATR is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary markets, noting that lead times may vary significantly. Ensure compatibility with existing PCB footprints and validate that alternative sources meet original quality standards before integration into new designs.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring a fixed 270 kHz switching frequency and synchronous buck topology. It is suitable for designs needing a 1.5 A output capability with an input voltage range up to 13.2V. Consider the 8-SOIC package constraints and the specific requirement for phase control if multiple phases are needed. Verify thermal management requirements given the 150°C maximum junction temperature rating.

DC DC Switching Controllers Part Context

The L6726ATR belongs to the L6726A family of DC-DC switching controllers from STMicroelectronics. This series focuses on efficient power conversion using synchronous rectification. The 'ATR' suffix typically denotes the tape and reel packaging format for automated assembly, distinguishing it from cut-tape or tube variants within the same functional specification.
