TPS61130PW Equivalent & Substitute Parts

Part Overview

The TPS61130PW is a dual-output power management IC (PMIC) from Texas Instruments that integrates a Step-Down/Step-Up (Buck/Boost) regulator and a Linear (LDO) regulator in a single 16-TSSOP package. This device is designed for applications requiring multiple regulated voltage outputs from a single input supply. The TPS61130PW has reached Last Time Buy status, making identification of suitable substitute components necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

The TPS61023DRLR is identified as a manufacturer-recommended substitute for the TPS61130PW. However, this substitution involves functional and topological differences that must be understood for proper component selection.

Key substitution parameters:

• Manufacturer: Texas Instruments (same)
• Topology: Boost (Step-Up only) versus dual-output Buck/Boost + LDO
• Number of Outputs: 1 versus 2
• Output Voltage Range: 2.2V ~ 5.5V versus 2.5V ~ 5.5V
• Output Current: 3A versus 300mA/320mA per output
• Switching Frequency: 1MHz versus 500kHz
• Package: SOT-563 versus 16-TSSOP
• Operating Temperature: -40°C ~ 125°C versus -40°C ~ 85°C
• Product Status: Active versus Last Time Buy

The TPS61023DRLR provides a single high-current boost output with adjustable voltage regulation, whereas the TPS61130PW provides dual independent outputs with mixed topologies. Direct functional equivalence is not possible due to architectural differences.

Parameter Comparison

Engineering Selection Recommendations

The TPS61023DRLR is an active product from Texas Instruments and maintains full RoHS3 compliance and unlimited MSL rating, matching the environmental and regulatory status of the TPS61130PW. The extended operating temperature range (-40°C ~ 125°C) of the TPS61023DRLR provides additional thermal margin compared to the TPS61130PW.

However, the TPS61023DRLR cannot serve as a direct pin-for-pin or functional replacement due to fundamental architectural differences. The TPS61130PW integrates two independent output regulators (Buck/Boost and LDO) in a single package, while the TPS61023DRLR provides only a single boost output. Applications requiring dual regulated outputs will require alternative component selection or circuit redesign.

For designs currently using the TPS61130PW, component substitution should be evaluated based on specific application requirements: if only a single boost output is needed, the TPS61023DRLR may be considered; if dual outputs are required, alternative dual-output PMIC solutions from Texas Instruments or other manufacturers must be identified.

Frequently Asked Questions (FAQ)

Q: Can the TPS61023DRLR directly replace the TPS61130PW in existing designs?

A: No. The TPS61023DRLR is a single-output boost regulator, while the TPS61130PW provides two independent outputs (Buck/Boost and LDO). Direct replacement is not possible without circuit redesign.

Q: What are the key differences in output capability?

A: The TPS61130PW provides two outputs with 300mA and 320mA capacity respectively. The TPS61023DRLR provides a single output with 3A capacity. Output voltage ranges differ slightly: TPS61130PW operates 2.5V ~ 5.5V, while TPS61023DRLR operates 2.2V ~ 5.5V.

Q: Are both devices RoHS compliant?

A: Yes. Both the TPS61130PW and TPS61023DRLR are ROHS3 compliant with unlimited MSL ratings (MSL 1).

Q: How do the switching frequencies compare?

A: The TPS61130PW operates at 500kHz, while the TPS61023DRLR operates at 1MHz. The higher frequency of the TPS61023DRLR may reduce external component size but may also increase switching losses in certain applications.

Q: What is the package difference?

A: The TPS61130PW uses a 16-TSSOP package (0.173" width, 4.40mm), while the TPS61023DRLR uses a smaller SOT-563 package. PCB layout and component placement will differ significantly.

Q: Why is the TPS61130PW at Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this product. Existing inventory is available, but no future production is planned. The TPS61023DRLR, being an active product, represents an alternative from the same manufacturer for new designs.
