LM2852XMXAX-1.8 Equivalent & Substitute Parts

Part Overview

The LM2852XMXAX-1.8 is a buck switching regulator IC from Texas Instruments' SIMPLE SWITCHER® series, designed for step-down voltage conversion with a fixed 1.8V output and 2A current capacity. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. The LM2852XMXAX-1.8/NOPB variant provides a direct functional equivalent with active product status and improved compliance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM2852XMXAX-1.8 is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 1.8V
• Output current rating of 2A
• Input voltage range of 2.85V to 5.5V
• Switching frequency of 1.5MHz
• Synchronous rectifier topology
• 14-PowerTSSOP package configuration
• Operating temperature range of -40°C to 125°C

The LM2852XMXAX-1.8/NOPB meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is product status and packaging format, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The LM2852XMXAX-1.8/NOPB is the appropriate selection for new designs and production applications. This variant maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The obsolete status of the original LM2852XMXAX-1.8 necessitates transition to the /NOPB variant for supply chain continuity and regulatory alignment. Both parts share the same base product number (LM2852) and are functionally interchangeable at the circuit level.

Frequently Asked Questions (FAQ)

Q: Are the LM2852XMXAX-1.8 and LM2852XMXAX-1.8/NOPB electrically identical?

A: Yes. Both parts deliver identical electrical performance with 1.8V fixed output, 2A current capacity, 1.5MHz switching frequency, and identical input voltage range (2.85V to 5.5V). The difference lies in product status and packaging format only.

Q: What is the significance of the /NOPB suffix?

A: The /NOPB designation indicates the part is supplied in Tape & Reel (TR) packaging format and is RoHS3 compliant. The original part uses bulk packaging and is RoHS non-compliant.

Q: Can I use the LM2852XMXAX-1.8/NOPB as a direct replacement in existing designs?

A: Yes. The /NOPB variant is a direct substitute with no circuit modifications required. Pin configuration, package footprint, and electrical characteristics are identical.

Q: Why is the original LM2852XMXAX-1.8 marked as obsolete?

A: Product obsolescence is determined by the manufacturer. The active /NOPB variant provides continued access to this functionality with improved compliance status.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both parts operate across the same temperature range (-40°C to 125°C) and share identical moisture sensitivity levels (MSL 1, Unlimited).

Q: What packaging considerations apply when switching from bulk to Tape & Reel format?

A: Tape & Reel packaging is standard for automated assembly processes. If your production environment uses manual placement or bulk component handling, coordinate with your assembly partner to confirm compatibility with existing processes.
