XRP6141ELMTR-F

Overview

The XRP6141ELMTR-F is a synchronous step-down controller from the MaxLinear XRP6141 series. It utilizes a Constant On-Time (COT) architecture and supports up to 35A output current. The device operates with an adjustable output voltage and features a switching frequency of 1 MHz. It is housed in a compact QFN-16 package suitable for surface mount installation. The component functions as a non-isolated DC-DC converter designed for network applications.

Feature Summary

• Implements Constant On-Time control topology for stable regulation
• Supports high current delivery for demanding power loads
• Designed specifically for telecommunications network equipment

Applications

• Telecommunications network infrastructure power systems
• High-density server power distribution units
• Industrial equipment requiring robust step-down conversion

Procurement Notes

Verify component authenticity through authorized channels due to potential supply chain variations. Confirm RoHS compliance status prior to integration, as documentation indicates variable regulatory information. Ensure compatibility with existing PCB layouts given the specific QFN-16 footprint requirements. Review latest manufacturer notices for any discontinuance or lifecycle changes affecting long-term availability.

Selection Notes

Select this controller when designing systems requiring high efficiency and fast transient response in space-constrained environments. The COT architecture simplifies external component selection compared to voltage mode controllers. Evaluate thermal management needs carefully, as the device supports significant current output within a small package profile. Ensure input voltage ranges align with system power rails for optimal performance.

Part Context
