Maxim Integrated MAX5090AATE+T High-Efficiency, Integrated Power-Supply IC

The MAX5090AATE+T from Maxim Integrated is a high-performance, integrated power-supply IC designed to deliver efficient and reliable power conversion for a wide range of applications. This device is particularly well-suited for space-constrained environments where a compact and energy-efficient power solution is required. The MAX5090AATE+T operates over a wide input voltage range and provides a fixed output voltage with high accuracy, making it an ideal choice for powering sensitive electronic circuits.

This power-supply IC integrates a high-voltage step-down DC-DC converter with a low-dropout regulator (LDO) to provide a dual-output voltage solution. The primary high-efficiency buck converter steps down voltages from up to 76V to a lower voltage, and the secondary LDO further refines the output to deliver a clean and stable voltage rail. This combination ensures that the MAX5090AATE+T can handle variations in input voltage while maintaining a consistent output.

The device comes in a compact, thermally-enhanced, 16-pin TQFN package, which allows for efficient heat dissipation and saves valuable board space. The MAX5090AATE+T also features a wide temperature range, making it suitable for industrial applications. With built-in thermal overload protection, cycle-by-cycle current limit, and under-voltage lockout, this IC offers robust protection features that ensure long-term reliability and safety for the end application.

Key features of the MAX5090AATE+T include:

• Wide 7.5V to 76V input voltage range
• Integrated high-voltage step-down converter and LDO
• High efficiency for reduced power loss and improved thermal performance
