MAX8997EWW+T

Overview

The MAX8997EWW+T is a specialized power management integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. Classified as a special-purpose voltage regulator, this component is designed for high-efficiency power conversion in compact form factors. It operates within a supply voltage range of 4.5 V to 28 V and supports an output current capability of up to 20 A. The device utilizes a buck topology with a switch frequency adjustable between 200 kHz and 1.4 MHz. It features a maximum duty cycle of 99.5% and provides an adjustable output voltage from 600 mV to 28 V. The IC is housed in a QFN-EP-20 package suitable for surface mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates a wide-input-voltage step-down switching controller optimized for high-current applications.
• Features adjustable switching frequency to allow optimization for efficiency or external component size.
• Includes internal compensation and protection mechanisms for stable operation in demanding environments.

Applications

• Industrial control systems requiring robust power regulation
• Telecommunications infrastructure equipment
• Automotive electronics and subsystems

Procurement Notes

Verify the specific suffix and tape/reel configuration against the manufacturer's latest datasheet before ordering. Confirm that the QFN-EP-20 package thermal pad requirements match your PCB layout design. Ensure compatibility with the intended input voltage range and load conditions. Check for any recent lifecycle status updates or alternative recommendations from Analog Devices.

Selection Notes

Select this component when a wide input voltage range and high output current are required in a small footprint. Consider the adjustable switching frequency feature if minimizing passive component size is a priority. Evaluate the thermal performance of the QFN-EP-20 package relative to your system's heat dissipation capabilities. Compare against other buck controllers if fixed-frequency operation or different pinouts are preferred.
