MP26060EQ-LF-Z

Overview

The MP26060EQ-LF-Z is a synchronous step-down DC/DC converter from Monolithic Power Systems. It integrates high-side and low-side N-channel MOSFETs to deliver efficient power conversion. The device supports an input voltage range of 4.5V to 18V and provides an adjustable output voltage. It operates with a fixed switching frequency of 600kHz, enabling the use of small external inductors and capacitors. The converter features cycle-by-cycle current limit, thermal shutdown, and undervoltage lockout for robust protection.

Feature Summary

• Integrated synchronous rectification with internal high-side and low-side MOSFETs
• Fixed 600kHz switching frequency for compact passive component selection
• Comprehensive protection mechanisms including thermal shutdown and current limiting

Applications

• Industrial equipment power distribution
• Consumer electronics battery charging systems
• Portable devices requiring efficient voltage regulation

Procurement Notes

Verify the specific suffix 'EQ-LF-Z' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering code matches the exact package type required for your PCB layout. Cross-reference the date code and lot number if traceability is critical for your supply chain requirements.

Selection Notes

Select this component when a compact solution with integrated power switches is needed for voltages up to 18V. The fixed 600kHz frequency balances efficiency and size. Consider the thermal performance of the QFN package under maximum load conditions. Verify that the required output current falls within the device's continuous rating specifications.

Part Context

This part belongs to the MP260xx series of synchronous buck converters. These devices are designed for applications requiring high efficiency and small footprint.
