MAX77961BEFV06+

Overview

The MAX77961BEFV06+ is a high-efficiency, synchronous step-down DC/DC converter from Maxim Integrated. It integrates two power switches and operates with an input voltage range of 2.5V to 5.5V. The device delivers up to 3A output current with adjustable switching frequencies from 400kHz to 2.2MHz. Key features include integrated inductor DCR sensing for precise current limit and thermal protection, along with programmable soft-start and frequency synchronization capabilities.

Feature Summary

• Integrates dual N-channel power switches for compact solution size
• Utilizes DCR current sensing for accurate overcurrent protection
• Supports frequency synchronization to reduce system noise

Applications

• Portable consumer electronics
• Tablets and smartphones
• Industrial control systems

Procurement Notes

Verify the specific suffix EFV06 against the manufacturer datasheet to confirm package type and temperature grade. Ensure compatibility with existing PCB footprint and thermal design requirements before procurement.

Selection Notes

Select this component when high efficiency at light loads and precise current limiting are required. Consider the available switching frequency options to balance EMI performance against passive component size.

Part Context

This part belongs to the MAX779xx family of buck converters designed for space-constrained applications. It offers improved transient response compared to previous generations while maintaining low quiescent current for battery-powered devices.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product line if supply constraints exist. Verify that any substitute maintains similar electrical characteristics and thermal performance.
