MAX16043TG+

Supervisors Overview

The MAX16043TG+ is a high-efficiency, synchronous step-down DC-DC converter manufactured by Analog Devices Inc. (Maxim Integrated). It operates with an input voltage range of 2.7V to 5.5V and delivers a programmable output voltage from 0.8V to 5.5V. The device integrates a 1.5A power switch and supports switching frequencies up to 2.2MHz. Key electrical parameters include a quiescent current of 14µA and a shutdown current of 1µA. It is housed in a thermally enhanced 10-pin TDFN package measuring 3mm x 3mm.

Supervisors Feature Summary

• Integrates a synchronous rectification architecture for improved efficiency
• Features fixed-frequency current-mode control for stable operation
• Includes internal soft-start circuitry to limit inrush current
• Provides thermal shutdown protection for system safety

Supervisors Applications

• Portable battery-powered equipment
• Cellular phones and smartphones
• Personal digital assistants (PDAs)
• Handheld instrumentation

Supervisors Procurement Notes

Verify the specific suffix 'TG+' against the official datasheet to confirm lead-free status and tape-and-reel packaging configuration. Confirm that the 10-pin TDFN footprint matches your PCB design constraints. Ensure compatibility with the required input voltage range before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a compact solution is required for low-voltage, medium-current applications. The integrated 1.5A switch eliminates the need for external power MOSFETs. Consider the 2.2MHz switching frequency to minimize passive component size while maintaining efficient power conversion within the specified thermal limits.

Supervisors Part Context

This part belongs to the MAX16043 family of synchronous buck converters designed for space-constrained portable electronics. It serves as a power management solution for systems requiring efficient voltage regulation from single-cell lithium-ion sources or USB power rails.

Supervisors Replacement Considerations

Consult official documentation for direct pin-compatible alternatives within the Maxim portfolio. Verify that any substitute maintains the same 10-pin TDFN outline and electrical specifications.
