MAX17603AUA+T

Overview

The MAX17603A is a high-efficiency, synchronous step-down DC-DC converter from Analog Devices (Maxim Integrated). It operates with an input voltage range of 2.5V to 5.5V and delivers up to 3A output current. The device integrates two N-channel power switches and features a fixed 2.2MHz switching frequency. It supports adjustable output voltages via an external resistor divider. Key protection features include overcurrent protection, thermal shutdown, and soft-start functionality. The component is housed in a compact 8-pin TDFN package.

Feature Summary

Integrated synchronous rectification for enhanced efficiency
Fixed high-frequency operation to minimize passive component size
Comprehensive protection mechanisms including thermal and current limiting

Applications

Portable consumer electronics
Industrial control systems
Infotainment modules

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging when placing orders. Confirm the 'A' variant specifications against the latest datasheet revision. Ensure compatibility with required input voltage ranges and thermal management solutions for the intended application environment before finalizing procurement.

Selection Notes

Select this component for applications requiring a compact solution with moderate current demands under 5.5V inputs. Consider the fixed 2.2MHz frequency for smaller inductor selection compared to lower-frequency alternatives. Evaluate thermal performance requirements given the integrated switch design and ensure adequate PCB copper area for heat dissipation.

Part Context

This part belongs to Maxim Integrated's family of synchronous buck converters designed for space-constrained portable devices. It complements other regulators in the portfolio by offering a balance between efficiency, size, and cost. The MAX17603 series provides a reliable power source for low-voltage digital logic and peripheral components in mobile and industrial sectors.
