MAX17428GTJ+T

Overview

The MAX17428GTJ+T is a single-phase switching controller designed for Intel IMVP-6.5 and GMCH processor power applications. It utilizes the Quick-PWM architecture to regulate output voltages with high precision. The device operates within an input voltage range of 2 V to 26 V, supporting output adjustments from 13 mV to 1.5 V. It features a fixed switching frequency of 600 kHz and functions reliably across an extended temperature range of -40°C to +105°C. The component is housed in a 32-pin TQFN package with an exposed pad for thermal management.

Procurement Notes

Verify the specific suffix designation carefully during procurement. Datasheets often list the tube-packaged variant (MAX17428GTJ+) as the primary reference. Confirm that the tape-and-reel version (MAX17428GTJ+T) matches the required packaging quantity and handling specifications for the manufacturing line before finalizing orders.

Selection Notes

Select this controller when designing for Intel IMVP-6.5 compliant processors requiring a single-phase solution. Ensure the application demands a 600 kHz switching frequency and an input voltage capability up to 26 V. Verify that the 32-TQFN package footprint aligns with the PCB layout constraints and thermal dissipation requirements of the target system.

Part Context

This component belongs to the Maxim Integrated PMIC portfolio focused on CPU power management. It serves as a specialized controller within the broader family of synchronous buck regulators. The device integrates essential protection features and drive circuits necessary for controlling external MOSFETs in high-current processor power stages.

Replacement Considerations

Public documentation confirms the MAX17428GTJ+ as the tube-packaged equivalent. No other verified substitute part numbers are available in public sources.
