MAX1718EEI+T

Overview

The MAX1718EEI+T is a switching controller designed for notebook CPU step-down applications, specifically supporting Intel Mobile Voltage Positioning (IMVP-II). It operates as a Buck topology converter with a single output. The device supports a switching frequency range of 200 kHz to 1 MHz and delivers up to 4 A output current. It provides an adjustable output voltage from 600 mV to 1.75 V with a maximum duty cycle of 100%. The component functions within a temperature range of -40°C to +85°C and is housed in a QSOP-28 surface-mount package.

Feature Summary

• Integrated control logic compliant with Intel IMVP-II specifications for mobile processor power management
• Capable of 100% duty cycle operation to maintain regulation at low input-to-output voltage differentials
• Includes shutdown functionality for power management flexibility

Applications

• Notebook CPU core voltage regulation
• Intel Mobile Voltage Positioning (IMVP-II) compatible power stages
• Step-down DC-DC conversion for mobile processors

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging versus the standard tube variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Check current availability as supply may be limited or restricted. Ensure the QSOP-28 package matches your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component for designs requiring IMVP-II compatibility and high-current CPU core regulation. Evaluate thermal performance given the 4 A output capability in the QSOP-28 package. Consider the 200 kHz to 1 MHz frequency range for inductor selection and efficiency optimization. Verify that the 600 mV to 1.75 V output range aligns with the target processor's VID requirements.
