XRP6142ELTR2-0-F

Overview

The XRP6142ELTR2-0-F is a non-isolated buck switching controller from MaxLinear, designed for low-voltage applications with DDR support. It features a fixed switching frequency of 1 MHz and delivers an output current capability of 15 A. The adjustable output voltage ranges from 0.5 V to 5 V. Operating within a temperature range of -40°C to +125°C, it utilizes a 16-pin QFN package. This component lacks a shutdown function and is classified under PMIC switching controllers.

Feature Summary

• Integrated DDR controller functionality for low-voltage power management
• High-frequency 1 MHz switching operation for compact design
• Robust thermal performance supporting high junction temperatures

Applications

• Low-voltage digital load power delivery
• DDR memory power regulation circuits
• Point-of-load conversion stages

Procurement Notes

Verify end-of-life status and discontinuation notices before integration. Confirm RoHS compliance details through official documentation. Check for alternative sourcing channels as standard distribution may be limited. Validate pinout compatibility with existing PCB layouts during the transition phase.

Selection Notes

Select this controller for designs requiring integrated DDR control logic. Ensure input voltage exceeds the minimum operating threshold. Verify inductor selection aligns with the 1 MHz frequency and 15 A current requirements. Consider the QFN-16 thermal pad for adequate heat dissipation at maximum load conditions.
