• Fully integrated synchronous design
• Wettable flank package for enhanced inspection

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial equipment power supplies
• Telecommunications infrastructure
• Point-of-load regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm the '+T' designation aligns with lead-free RoHS compliance requirements. Ensure the 17-PowerWFQFN footprint matches the target PCB layout dimensions. Validate that the fixed 3.3V output variant meets the system voltage specifications before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when wide input voltage coverage up to 36V is required alongside high current delivery. The integrated switch design reduces external component count compared to non-integrated alternatives. Consider the thermal performance of the PowerWFQFN package for high-density applications requiring efficient heat dissipation without additional heatsinking.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the MAX2640x family of tiny, low EMI emission synchronous buck converters. The series offers various current ratings and output configurations. The MAX26405 specifically supports up to 6A output, distinguishing it from lower-current variants in the same product line while sharing the core Silent Switcher architecture.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for pin-compatible alternatives within the MAX26404 or MAX26406 families if different current ratings are needed. Verify that any substitute maintains the 17-PowerWFQFN package and wettable flank construction for direct board replacement.
