TPS54880PWP Equivalent & Substitute Parts

Part Overview

The TPS54880PWP is a buck switching regulator IC from Texas Instruments' SWIFT™ series, designed for positive adjustable step-down voltage regulation with 8A output current capability. This device operates across a 4V to 6V input range and supports adjustable output voltage from 0.9V to 3.3V. The TPS54880PWP is currently in Last Time Buy status, making identification of functionally equivalent alternatives essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS54880PWP is determined by the following critical parameters:

• Topology & Function: Buck switching regulator with step-down capability
• Output Configuration: Positive adjustable voltage regulation
• Output Current Capability: Minimum 8A required
• Input Voltage Compatibility: Support for 4V to 6V input range
• Output Voltage Range: Adjustable output spanning at least 0.9V to 3.3V
• Synchronous Rectification: Integrated synchronous rectifier required
• Regulatory Compliance: ROHS3 compliance and EAR99 classification

The TPS62871QWRXSRQ1 qualifies as a manufacturer-recommended substitute based on these parameters. While it operates across a wider input range (2.7V to 6V) and supports lower minimum output voltage (0.4V), it maintains compatibility with the TPS54880PWP's core operating envelope and exceeds the 8A current requirement with 9A capability.

Parameter Comparison

Engineering Selection Recommendations

The TPS62871QWRXSRQ1 is designated as the manufacturer-recommended substitute for the TPS54880PWP. Selection between these devices should be based on the following engineering criteria:

Choose TPS62871QWRXSRQ1 when:

• Active product status is required for long-term availability
• Automotive-grade qualification (AEC-Q100) is specified
• Extended operating temperature range (-40°C to 125°C) is necessary
• Higher switching frequency operation (up to 3MHz) is acceptable
• PCB space constraints favor a smaller 16-TFQFN package over 28-PowerTSSOP
• Lower minimum output voltage (0.4V) provides additional design flexibility

Retain TPS54880PWP when:

• Existing designs are locked to the 28-PowerTSSOP package footprint
• Lower switching frequency (350kHz) is preferred for EMI or thermal considerations
• Current design has completed qualification and substitution is not required

Both devices maintain ROHS3 compliance and EAR99 classification. The TPS62871QWRXSRQ1's automotive qualification and active product status provide advantages for new designs and long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the TPS62871QWRXSRQ1 directly replace the TPS54880PWP in existing designs?

A: Functional substitution is possible for applications within the overlapping operating envelope (4V to 6V input, 0.9V to 3.3V output, up to 8A load). However, package differences (28-PowerTSSOP vs. 16-TFQFN) require PCB layout redesign. Switching frequency differences (350kHz vs. 1.5MHz to 3MHz) may affect filter component selection and EMI characteristics.

Q: What are the key electrical differences between these devices?

A: The TPS62871QWRXSRQ1 offers wider input voltage range (2.7V minimum vs. 4V), lower minimum output voltage (0.4V vs. 0.9V), higher output current (9A vs. 8A), and higher selectable switching frequencies. The TPS54880PWP operates at a fixed 350kHz switching frequency.

Q: Does package size affect substitution feasibility?

A: Yes. The TPS54880PWP uses a 28-PowerTSSOP package (0.173" × 4.40mm width), while the TPS62871QWRXSRQ1 uses a smaller 16-TFQFN package (2.55mm × 4.65mm). Direct footprint replacement is not possible; PCB redesign is required.

Q: Are both devices RoHS compliant?

A: Yes. Both the TPS54880PWP and TPS62871QWRXSRQ1 are ROHS3 compliant and carry EAR99 export classification.

Q: What is the significance of the TPS54880PWP's Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this product. The TPS62871QWRXSRQ1, with Active status, is recommended for new designs and long-term procurement to ensure supply chain continuity.

Q: Does the TPS62871QWRXSRQ1's automotive qualification matter for non-automotive applications?

A: AEC-Q100 automotive qualification indicates enhanced reliability testing and stricter quality standards. For non-automotive applications, this qualification provides additional assurance of device robustness but is not a requirement for substitution eligibility.
