MAX15301ETI+

DC DC Switching Controllers Overview

The MAX15301ETI+ is a synchronous buck DC-DC controller IC from Analog Devices, designed for digital power applications. It features a 4.5V to 14V supply voltage range and operates within a -40°C to +85°C temperature range. The device utilizes a 32-TQFN (5x5) surface-mount package and supports PMBus serial interface communication. Key control features include current limit protection, enable functionality, and power good signaling. It functions as an auto-compensating point-of-load controller with clock synchronization capabilities.

DC DC Switching Controllers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required pinout and thermal characteristics. Check for obsolescence notices as this product may be discontinued. Ensure proper handling procedures are followed due to the sensitive nature of the TQFN package. Validate that the procurement source provides valid traceability documentation.

DC DC Switching Controllers Selection Notes

Select this component when a digital, PMBus-enabled buck controller is required for high-reliability applications. Consider the 32-TQFN package size for space-constrained designs. Evaluate the need for clock synchronization if multiple phases are used in parallel. Assess compatibility with existing FPGA or base-station power architectures before finalizing the design choice.

DC DC Switching Controllers Part Context
