Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS61032PWPR is determined by the following critical parameters:

Functional Requirements:

• Boost (step-up) topology with positive output configuration
• Synchronous rectification capability
• Surface mount technology

Electrical Specifications:

• Input voltage compatibility: minimum 0.5V to 5.5V range (TPS61032PWPR operates 1.8V to 5.5V)
• Output voltage: fixed or adjustable 5V capability
• Output current: minimum 2.5A to 3.6A range
• Switching frequency: 550kHz to 1MHz range

Physical & Environmental:

• Surface mount package compatibility
• Operating temperature range: -40°C to 125°C (extended range preferred)
• RoHS3 compliance
• Moisture sensitivity level: 1 or 2

The identified substitute parts (TLV61070ADBVR and TPS61023DRLR) meet these core substitution criteria while offering adjustable output voltage configurations and improved temperature operating ranges.

Parameter Comparison

Engineering Selection Recommendations

TPS61023DRLR is the primary substitute for the TPS61032PWPR. It maintains the highest output current specification (3A versus 2.5A in the TLV61070ADBVR), closest to the original 3.6A rating. The TPS61023DRLR operates at 1MHz switching frequency, provides adjustable output voltage from 2.2V to 5.5V, and extends the operating temperature range to -40°C to 125°C. The device is in Active product status with unlimited MSL rating, ensuring long-term availability and supply chain stability. The SOT-563 package is significantly smaller than the original 16-PowerTSSOP, requiring PCB layout redesign.

TLV61070ADBVR serves as a secondary substitute when lower output current (2.5A) is acceptable for the application. This device offers the widest input voltage range (0.5V minimum) and the smallest package footprint (SOT-23-6). It is suitable for applications with reduced power requirements or space-constrained designs. The unlimited MSL rating and Active product status provide procurement advantages.

Both substitutes are ROHS3 compliant and manufactured by Texas Instruments, ensuring regulatory alignment and design continuity.

Frequently Asked Questions (FAQ)

Q: Can the TPS61023DRLR directly replace the TPS61032PWPR without circuit modifications?

A: The TPS61023DRLR is functionally compatible but requires circuit redesign. The primary differences are package type (SOT-563 versus 16-PowerTSSOP), adjustable versus fixed output voltage, and reduced output current (3A versus 3.6A). PCB layout and external component values must be recalculated according to the TPS61023DRLR datasheet.

Q: What is the impact of switching frequency differences between these devices?

A: The TPS61032PWPR operates at 600kHz, while the TPS61023DRLR operates at 1MHz and the TLV61070ADBVR at 550kHz or 1MHz. Higher switching frequency reduces output filter size but increases switching losses. Lower frequency reduces losses but requires larger filtering components. Selection depends on application power budget and PCB space constraints.

Q: Are the substitute parts suitable for the same input voltage range?

A: The TPS61032PWPR operates from 1.8V to 5.5V input. Both substitutes operate from 0.5V to 5.5V, providing extended low-voltage capability. Applications requiring minimum 1.8V input are fully compatible with either substitute.

Q: How do package differences affect design implementation?

A: The TPS61032PWPR uses 16-PowerTSSOP (0.173" width), while TPS61023DRLR uses SOT-563 and TLV61070ADBVR uses SOT-23-6. Smaller packages reduce PCB footprint but may increase assembly complexity. Thermal performance differs; the 16-PowerTSSOP provides better heat dissipation than smaller packages. Thermal analysis is required for high-current applications.

Q: What are the implications of adjustable versus fixed output voltage?

A: The TPS61032PWPR provides fixed 5V output. Both substitutes offer adjustable output from 2.2V to 5.5V, requiring external resistor dividers for voltage setting. This adds design flexibility but increases component count and requires precise resistor selection for output voltage accuracy.

Q: Are there supply chain advantages to using the substitute parts?

A: Both TPS61023DRLR and TLV61070ADBVR are in Active product status with significantly higher inventory levels (10,300 and 349,731 units respectively) compared to the TPS61032PWPR (Last Time Buy status with 22,080 units). The substitutes offer superior long-term availability and reduced procurement risk.
