MAX15003ATM+T

DC DC Switching Controllers Overview

The MAX15003ATM+T is a triple-output synchronous buck DC-DC switching controller manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 5.5V to 23V and supports adjustable switching frequencies from 200kHz to 2.2MHz. The device features three positive output channels housed in a 48-TQFN (7x7) package with an exposed pad. Key control characteristics include current limiting, enable, frequency control, phase control, power good, reset, and tracking functions. It is designed for surface mount installation and operates at junction temperatures between -40°C and 125°C.

DC DC Switching Controllers Feature Summary

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the component meets RoHS3 compliance requirements for your region. Ensure the 48-TQFN footprint matches your PCB layout guidelines. Check for any lead-free soldering profile restrictions specified in the datasheet. Validate that the operating temperature range aligns with your environmental specifications.

DC DC Switching Controllers Selection Notes

Select this controller when multiple synchronized buck outputs are required from a single IC. Consider the 200kHz to 2.2MHz frequency range for optimizing efficiency versus size. Evaluate the 48-pin TQFN package for thermal performance and board space constraints. Verify input voltage compatibility within the 5.5V to 23V range. Assess the need for integrated phase control and tracking features for system stability.
