XR78020ELTR-F

Overview

The XR78020ELTR-F is a synchronous buck converter DrMOS power module manufactured by MaxLinear. It integrates a half-bridge driver and power stage into a single component. The device supports an input voltage range of 4.5V to 17V and delivers up to 20A of output current per channel. It utilizes a 27-QFN (4x5) package for compact surface-mount installation.

Feature Summary

• Integrates half-bridge driver with synchronous buck power stage in a DrMOS configuration
• Supports high-current delivery up to 20A per channel
• Operates within a wide input voltage range from 4.5V to 17V

Applications

• Point-of-load regulation for high-current digital loads
• Server and storage subsystem power distribution
• Industrial equipment requiring compact synchronous step-down conversion

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm the 27-QFN (4x5) footprint matches the PCB layout requirements. Ensure the 4.5V minimum input voltage aligns with the system supply rails. Check for RoHS compliance documentation if required by regulatory standards.

Selection Notes

Select this component for designs requiring integrated high-current synchronous rectification without external gate drivers. The DrMOS architecture reduces board space compared to discrete solutions. Verify thermal management capabilities for the 20A output requirement within the QFN package constraints.
