TPS61282AYFFR Equivalent & Substitute Parts

Part Overview

The TPS61282AYFFR is a boost switching regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. This device functions as a step-up converter with programmable output, delivering 4A switch current from a 2.3V to 4.85V input range to produce 2.85V to 4.4V output. The TPS61282AYFFR carries an Obsolete product status, necessitating identification of functionally equivalent alternatives for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS61282AYFFR is determined by strict alignment across the following critical parameters:

Mandatory Matching Parameters:

• Function: Step-Up (Boost topology)
• Output Configuration: Positive
• Output Type: Programmable
• Number of Outputs: 1
• Voltage - Input Range: 2.3V to 4.85V
• Voltage - Output Range: 2.85V to 4.4V
• Switching Frequency: 2.3MHz
• Synchronous Rectifier: Yes
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 16-UFBGA, DSBGA
• Supplier Device Package: 16-DSBGA (1.67x1.67)
• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)

Allowable Variation:

• Current - Output: 4A or higher (5A acceptable as higher capacity)
• Product Status: Active, Not For New Designs, or Obsolete
• Packaging Format: Cut Tape (CT) & Digi-Reel® or Tape & Reel (TR)

Substitute parts are grouped into two categories: Direct Substitutes (identical 4A output current) and Parametric Equivalents (5A output current, higher capacity).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (4A Output Current): TPS61282AYFFT and TPS61282YFFT maintain identical output current specifications to the TPS61282AYFFR. Both parts are classified as Obsolete, matching the status of the primary part. Selection between these variants depends on packaging format availability: TPS61282AYFFT is supplied in Tape & Reel (TR) format, while TPS61282YFFT is supplied in Cut Tape (CT) & Digi-Reel® format.

Parametric Equivalents (5A Output Current): TPS61280DYFFR and TPS61280DYFFT provide higher output current capacity (5A) while maintaining all other electrical and thermal specifications. TPS61280DYFFR carries Active product status and is available in Cut Tape (CT) & Digi-Reel® format with 9415 units in stock. TPS61280DYFFT also carries Active status and is supplied in Tape & Reel (TR) format with 1483 units in stock. These parts are suitable for applications where increased current headroom is beneficial.

All substitute candidates maintain ROHS3 compliance, MSL Level 1 (Unlimited), and identical operating temperature ranges (-40°C ~ 85°C). Package geometry remains constant at 16-DSBGA (1.67x1.67), ensuring mechanical and thermal compatibility.

Frequently Asked Questions (FAQ)

Q: Can TPS61280 series parts replace TPS61282AYFFR directly? A: Yes, TPS61280 series parts with matching electrical specifications (2.3V to 4.85V input, 2.85V to 4.4V output, 2.3MHz switching frequency, programmable output, synchronous rectifier) are functionally equivalent. The primary difference is increased output current capacity (5A versus 4A), which does not prevent substitution in applications designed for 4A operation.

Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging? A: Both packaging formats contain identical die and electrical performance. Cut Tape (CT) & Digi-Reel® format is supplied on cut tape with individual component reels, suitable for lower-volume or mixed-component orders. Tape & Reel (TR) format provides continuous tape packaging, optimized for high-volume automated assembly. Selection depends on production volume and assembly equipment compatibility.

Q: Are all substitute parts ROHS3 compliant? A: Yes, all listed substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the environmental and regulatory specifications of the TPS61282AYFFR.

Q: Which substitute part has the best availability? A: TPS61280AYFFR offers the highest inventory level at 20200 units, followed by TPS61280YFFR at 17700 units. Both are TPS61280 base variants with 5A output current. TPS61280DYFFR, with Active product status and 9415 units in stock, represents the recommended choice for new designs requiring long-term supply assurance.

Q: Can I use a 5A-rated part in a 4A application? A: Yes. A 5A-rated device operates within specification in a 4A application. The higher current rating provides additional design margin and thermal headroom without compromising performance or reliability.
