MAX1701EEE Equivalent & Substitute Parts

Part Overview

The MAX1701EEE is a boost switching regulator IC from Analog Devices Inc./Maxim Integrated, classified as a Power Management (PMIC) component. It functions as a step-up converter with positive adjustable output, designed to deliver 1.1A switch current across a single output channel. The device operates across an input voltage range of 0.7V to 5.5V with adjustable output voltage from 2.2V to 5.5V at a switching frequency of 300kHz.

The MAX1701EEE is currently listed as obsolete. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this regulator topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX1701EEE is determined by strict equivalence across the following critical parameters:

• Topology & Function: Boost (step-up) switching regulator with positive adjustable output
• Electrical Specifications: Input voltage range 0.7V–5.5V, adjustable output 2.2V–5.5V, 1.1A switch current, 300kHz switching frequency
• Output Configuration: Single positive adjustable output channel
• Synchronous Rectifier: Non-synchronous design
• Package & Mounting: 16-SSOP surface mount package (0.154", 3.90mm width)
• Operating Temperature Range: -40°C to 85°C

The MAX1701EEE+ qualifies as a direct substitute based on identical electrical performance, topology, output configuration, and package specifications. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The MAX1701EEE+ is the direct equivalent substitute for the MAX1701EEE. Both devices are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications, topology, and package configuration.

The MAX1701EEE+ offers two significant advantages:

1. Product Status: The MAX1701EEE+ maintains active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity.

2. Compliance: The MAX1701EEE+ is ROHS3 compliant, whereas the original MAX1701EEE is RoHS non-compliant. This distinction is critical for applications subject to RoHS regulations or customer compliance requirements.

For new designs or production requiring RoHS compliance, the MAX1701EEE+ is the appropriate selection. For legacy system maintenance where RoHS compliance is not a constraint, either part is electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the MAX1701EEE+ directly replace the MAX1701EEE in existing designs?

A: Yes. The MAX1701EEE+ is electrically and mechanically identical to the MAX1701EEE. Both devices feature the same boost regulator topology, electrical specifications (0.7V–5.5V input, 2.2V–5.5V adjustable output, 1.1A switch current, 300kHz switching frequency), and 16-SSOP package. No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The MAX1701EEE is obsolete and RoHS non-compliant, while the MAX1701EEE+ is an active product with ROHS3 compliance. Electrical performance and package specifications are identical.

Q: Are there any package or mounting differences?

A: Both parts use the same 16-SSOP (0.154", 3.90mm width) surface mount package. The MAX1701EEE+ is supplied in tube packaging, while the original MAX1701EEE packaging is not specified.

Q: Does the MAX1701EEE+ support the same input and output voltage ranges?

A: Yes. Both parts operate with input voltage from 0.7V to 5.5V and provide adjustable output voltage from 2.2V to 5.5V. Operating temperature range is identical at -40°C to 85°C.

Q: Is RoHS compliance a consideration for my application?

A: If your application or customer requirements mandate RoHS compliance, the MAX1701EEE+ is the required selection. The original MAX1701EEE does not meet RoHS standards.
