MAX17672FATB+T

Overview

The MAX17672FATB+T is a synchronous step-down DC-DC converter from Analog Devices/Maxim Integrated. It operates with an input voltage range of 4.5V to 60V and provides a fixed output current capability of 150mA. The device integrates high-side and low-side N-channel power switches within a compact TDFN package. Key electrical parameters include an operating temperature range of -40°C to +125°C and a switching frequency of 1.2MHz. The regulator supports an output voltage range typically starting from 800mV up to the programmed limit, ensuring efficient power conversion for space-constrained applications.

Feature Summary

• Integrates high-side and low-side N-channel power switches for compact design
• Supports wide 4.5V to 60V input voltage range
• Features fixed 1.2MHz switching frequency for small external components
• Includes thermal shutdown and overcurrent protection

Applications

• Distributed power supply regulation in industrial systems
• Point-of-load conversion for base station equipment
• Power management in automotive electronics
• Battery-powered devices requiring wide input range

Procurement Notes

Verify the specific suffix 'FATB' corresponds to the required tape-and-reel packaging and temperature grade. Confirm RoHS compliance status through official documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices. Ensure the ordering part number matches the exact pinout and thermal pad requirements for your PCB layout.

Selection Notes

Select this component when a wide input voltage range up to 60V is required with moderate output current. The fixed 1.2MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the TDFN package size constraints and thermal dissipation capabilities relative to your application's ambient temperature and load profile.

Part Context

This part belongs to the MAX1767x family of synchronous buck converters designed for high-voltage inputs. It shares architectural similarities with other members like the MAX17671 and MAX17673 but differs in output current ratings and specific feature sets. The family targets applications needing robust power regulation in harsh environments.

Replacement Considerations

Direct substitutes may include MAX17671FATB+T or MAX17673ATI+T depending on current requirements. Verify pin compatibility and thermal performance before substitution. Cross-reference datasheets for differences in switching frequency and protection features.
