XRP6142EL0-5-F

Overview

The XRP6142EL0-5-F is a synchronous buck switching controller designed for DDR voltage regulation. It operates with an input voltage range of 1V to 5.5V and provides an adjustable output from 0.5V to 5V. The device supports up to 15A output current at a fixed 1MHz switching frequency. Packaged in a 16-pin QFN (3x3mm) with an exposed pad, it functions as a non-isolated power management IC. The component is rated for operation between -40°C and +125°C.

Feature Summary

• Integrated synchronous buck controller optimized for low-voltage DDR applications
• Fixed 1MHz switching frequency for compact external component sizing
• Wide input voltage compatibility supporting various system power rails

Applications

• DDR memory subsystem voltage regulation
• Low-voltage point-of-load conversion
• Embedded system power management

Procurement Notes

Verify the specific suffix 'L0-5' against project requirements, as it denotes a fixed pinout or variant distinct from other XRP6142 configurations. Confirm end-of-life status with the manufacturer before finalizing designs. Ensure the 16-QFN package footprint matches the PCB layout constraints. Validate thermal performance under maximum load conditions given the small package size.

Selection Notes

Select this controller when designing for DDR interfaces requiring precise voltage control within a 1V to 5.5V input range. The 15A current capability suits high-density memory modules. Consider the 16-QFN package for space-constrained layouts. Verify that the fixed 1MHz frequency aligns with EMI requirements and inductor selection guidelines provided in the datasheet.

Part Context

This part belongs to the MaxLinear XRP6142 series of specialized power management ICs. It is categorized under switching controllers and step-down regulators. The series targets applications needing efficient, low-profile power solutions for sensitive digital logic and memory components.

Replacement Considerations

Check for direct substitutes within the XRP6142 family, such as XRP6142ELTR1-0-F, noting differences in packaging or suffix specifications. Evaluate alternative DDR controllers from other manufacturers if supply is restricted, ensuring pin compatibility and electrical parameters match.
