LM2852YMXA-3.3 Equivalent & Substitute Parts

Part Overview

The LM2852YMXA-3.3 is a buck switching regulator IC from Texas Instruments' SIMPLE SWITCHER® series, designed for step-down voltage conversion with a fixed 3.3V output and 2A current capacity. This device operates across an input voltage range of 2.85V to 5.5V and features a 500kHz switching frequency with integrated synchronous rectification. The main part number is currently in Last Time Buy status, making identification of suitable alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LM2852YMXA-3.3 is determined by strict alignment across the following critical parameters:

• Fixed output voltage of 3.3V
• Minimum output current rating of 2A
• Input voltage range compatibility (2.85V to 5.5V minimum)
• Buck topology with synchronous rectification
• 14-PowerTSSOP package footprint
• Operating temperature range of -40°C to 125°C
• Surface mount configuration

Only parts meeting all these specifications are classified as direct substitutes. Packaging variants (such as tube versus alternative packaging formats) do not affect functional substitutability when the core electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The LM2852YMXA-3.3/NOPB is the manufacturer-recommended substitute for the LM2852YMXA-3.3. Both parts are identical in electrical specifications, package configuration, and compliance certifications. The primary distinction is product lifecycle status: the original part number is designated Last Time Buy, while the /NOPB variant maintains Active status with Texas Instruments.

Selection between these part numbers should be based on procurement timeline and inventory availability. The /NOPB variant, carrying Active product status, provides extended supply assurance for new designs and ongoing production requirements. Both parts satisfy ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: What does the /NOPB suffix indicate? A: The /NOPB designation indicates "No Plumbum" (lead-free) packaging. This is a standard Texas Instruments notation for RoHS-compliant variants and does not affect electrical performance or pin compatibility.

Q: Can the LM2852YMXA-3.3/NOPB be used as a direct replacement for LM2852YMXA-3.3? A: Yes. Both parts share identical electrical specifications, output voltage, current rating, input voltage range, switching frequency, package footprint, and operating temperature range. No circuit modifications are required.

Q: Are there differences in packaging format between these part numbers? A: The main part number (LM2852YMXA-3.3) does not specify packaging format in the provided data. The substitute part (LM2852YMXA-3.3/NOPB) is supplied in Tube packaging. Both use the same 14-PowerTSSOP physical package. Packaging format affects handling and storage but not functional compatibility.

Q: Why is the original part number in Last Time Buy status? A: Last Time Buy status indicates Texas Instruments is discontinuing this specific part number variant. The /NOPB variant remains in Active production, making it the recommended choice for new designs and future procurement.

Q: What are the critical parameters for substitution? A: Direct substitution requires matching: 3.3V fixed output voltage, 2A minimum output current, 2.85V to 5.5V input range, 500kHz switching frequency, synchronous rectification, 14-PowerTSSOP package, and -40°C to 125°C operating temperature.

Q: Are compliance certifications identical between these parts? A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited). Regulatory and environmental compliance is equivalent.
