MAX15003ATM+

DC DC Switching Controllers Overview

The MAX15003ATM+ is a three-channel 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 utilizes a 48-TQFN (7x7) package with an exposed pad for thermal management. Designed for industrial applications, it functions reliably across a junction temperature range of -40°C to 125°C.

DC DC Switching Controllers Feature Summary

• Integrates three independent synchronous buck channels for multi-rail power distribution
• Supports clock synchronization and phase control for noise reduction
• Includes comprehensive protection features such as current limiting and thermal shutdown

DC DC Switching Controllers Applications

• Industrial automation systems requiring multiple regulated voltage rails
• Telecommunications infrastructure equipment
• Embedded computing platforms with complex power sequencing needs

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'ATM+' against the official Maxim Integrated part numbering system to confirm temperature grade and packaging details. Ensure compatibility with the required 48-TQFN footprint during PCB layout. Confirm RoHS compliance status through the manufacturer's latest environmental declaration documents before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component when designing systems requiring three synchronized buck converters from a single input source. Evaluate the 200kHz to 2.2MHz frequency range against inductor size constraints and efficiency targets. Consider the 48-TQFN package thermal performance relative to the expected load currents and ambient operating conditions.

DC DC Switching Controllers Part Context
