MAX17515ELI+

Overview

The MAX17515ELI+ is a synchronous step-down DC-DC converter from the Himalaya series, designed as a high-efficiency power module. It accepts an input voltage range of 2.4V to 5.5V and delivers up to 5A output current. The device integrates power switches and control circuitry into a compact 28-PowerBLGA (6.5x10mm) package. Key electrical characteristics include a fixed switching frequency and integrated protection features such as overcurrent and thermal shutdown.

Feature Summary

• Integrates synchronous buck power stage and controller in a single module
• High efficiency design optimized for low noise applications
• Compact surface-mount PowerBLGA package for space-constrained designs

Applications

• FPGA core voltage regulation
• Industrial distributed power systems
• Point-of-load conversion for high-current digital loads

Procurement Notes

Verify component status carefully as this part may be obsolete or limited supply. Confirm exact package marking and date code against official datasheets. Ensure compatibility with existing PCB footprints and thermal management requirements before procurement.

Selection Notes

Select this module when high current density and minimal board space are critical. Consider input voltage stability within the 2.4V to 5.5V range. Evaluate thermal performance under maximum load conditions due to the dense integration of power components in the small footprint.

Part Context

Part of the Maxim Integrated Himalaya family of complete switch-mode power supplies. Designed to simplify power architecture by integrating passive components and control logic. Offers improved transient response compared to discrete solutions while reducing overall system complexity and assembly time.

Replacement Considerations

Check for active equivalents in the MAX175xx series. Verify pinout compatibility if substituting with similar Himalaya modules. Confirm that alternative parts support the required 5A output and input voltage range.
