LM2852XMXAX-1.5 Equivalent & Substitute Parts

Part Overview

The LM2852XMXAX-1.5 is a buck switching regulator IC from Texas Instruments' SIMPLE SWITCHER® series, designed for step-down voltage conversion with a fixed 1.5V output and 2A output current capability. This device operates across an input voltage range of 2.85V to 5.5V and features a 1.5MHz switching frequency with integrated synchronous rectification.

The LM2852XMXAX-1.5 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and access components with active manufacturing support and current compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM2852XMXAX-1.5 is determined by strict equivalence across the following critical parameters:

• Function and topology (step-down buck converter)
• Output configuration (positive, fixed 1.5V)
• Output current capability (2A minimum)
• Input voltage range (2.85V to 5.5V)
• Switching frequency (1.5MHz)
• Synchronous rectification capability
• Operating temperature range (-40°C to 125°C)
• Package type (14-PowerTSSOP / 14-HTSSOP)
• Mounting type (surface mount)

The LM2852XMXAX-1.5/NOPB is identified as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The LM2852XMXAX-1.5/NOPB is the direct substitute for the obsolete LM2852XMXAX-1.5. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility.

The primary advantage of the LM2852XMXAX-1.5/NOPB is its active product status and ROHS3 compliance, compared to the non-compliant status of the original part. The /NOPB designation indicates lead-free, halogen-free construction. The Tape & Reel packaging format of the substitute part is standard for production-volume applications.

Selection between these parts should be based on supply chain availability, compliance requirements, and packaging format needs. The substitute part is recommended for new designs and ongoing production due to its active status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Are the LM2852XMXAX-1.5 and LM2852XMXAX-1.5/NOPB electrically identical?

A: Yes. Both parts are functionally equivalent with identical electrical specifications, including input voltage range (2.85V to 5.5V), fixed 1.5V output, 2A output current, 1.5MHz switching frequency, and operating temperature range (-40°C to 125°C).

Q: What does the /NOPB suffix indicate?

A: The /NOPB suffix designates a lead-free, halogen-free part that meets ROHS3 compliance requirements. The original LM2852XMXAX-1.5 does not carry this designation and is RoHS non-compliant.

Q: Can I use the LM2852XMXAX-1.5/NOPB as a direct replacement in existing designs?

A: Yes. The substitute part is pin-for-pin compatible and functionally equivalent. No circuit modifications are required. The 14-PowerTSSOP package dimensions and pinout are identical.

Q: What is the difference in packaging between these parts?

A: The LM2852XMXAX-1.5/NOPB is supplied in Tape & Reel (TR) format, which is standard for automated assembly and production volumes. The original part's packaging format is unspecified in the available data.

Q: Why is the original LM2852XMXAX-1.5 marked as obsolete?

A: Obsolete status indicates that Texas Instruments has discontinued active manufacturing and support for this specific part number. The LM2852XMXAX-1.5/NOPB remains in active production and is the recommended alternative.

Q: Are there any compliance or regulatory differences between these parts?

A: Yes. The LM2852XMXAX-1.5/NOPB is ROHS3 compliant and lead-free, while the original LM2852XMXAX-1.5 is RoHS non-compliant. Both parts maintain identical REACH and ECCN classifications.
