MAX1714BEEE Equivalent & Substitute Parts

Part Overview

The MAX1714BEEE is a Buck Regulator Positive Output Step-Down DC-DC Controller IC manufactured by Analog Devices Inc./Maxim Integrated. This power management IC operates as a transistor driver for step-down topology applications with a single positive output phase. The device is classified as obsolete, which necessitates identification of functionally equivalent alternatives for new designs or production continuity. The MAX1714BEEE+ serves as the direct active substitute, offering identical electrical and mechanical specifications with improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX1714BEEE is determined by strict equivalence across the following critical parameters:

Topology and Function: Both the main part and substitute must operate as buck regulators with positive output step-down DC-DC controller functionality and transistor driver output type.

Electrical Specifications: Supply voltage range (4.5V ~ 5.5V), switching frequency options (200kHz, 300kHz, 450kHz, 600kHz), duty cycle capability (100% maximum), and control features (Current Limit, Enable, On Time Control, Power Good) must be identical.

Mechanical Compatibility: Package type (16-SSOP with 0.154" / 3.90mm width) and surface mount mounting type must match exactly to ensure PCB layout compatibility.

Output Configuration: Single positive output with one phase is a fixed requirement for substitution eligibility.

The MAX1714BEEE+ qualifies as a direct substitute because it maintains identical electrical and mechanical parameters while offering active product status and improved compliance certifications.
