TPS62562DRVT Equivalent & Substitute Parts

Part Overview

The TPS62562DRVT is an active buck switching regulator IC from Texas Instruments, designed for step-down voltage conversion with a fixed 1.8V output. This device delivers 600mA output current and operates across a 2.5V to 5.5V input range with a switching frequency of 2.25MHz. The part is housed in a 6-WDFN exposed pad surface mount package and includes integrated synchronous rectification for improved efficiency. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or application-specific qualification needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TPS62562DRVT is determined by strict alignment of core electrical and mechanical parameters. The following criteria define valid substitutes:

Critical Parameters for Substitution:

• Output voltage (fixed at 1.8V)
• Output current capability (600mA minimum)
• Input voltage range compatibility (must encompass or match 2.5V to 5.5V)
• Switching frequency (2.25MHz)
• Synchronous rectifier presence
• Package type (6-WDFN exposed pad)
• Topology (buck converter)

The TPS62261TDRVRQ1 qualifies as a direct substitute based on these parameters. Both devices share identical output specifications, switching frequency, synchronous rectification, and package configuration. The substitute part extends the input voltage range to 2V to 6V and the operating temperature range to -40°C to 105°C, providing broader application flexibility. The substitute includes automotive-grade qualification (AEC-Q100), making it suitable for automotive and high-reliability applications where the original part may not meet qualification requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS62562DRVT and TPS62261TDRVRQ1 are active products from Texas Instruments with full RoHS3 compliance. Selection between these parts depends on application requirements and qualification status.

The TPS62562DRVT is suitable for commercial-grade applications operating within the specified 2.5V to 5.5V input range and -40°C to 85°C temperature envelope.

The TPS62261TDRVRQ1 is the appropriate choice for automotive applications or systems requiring AEC-Q100 qualification. This part also provides extended input voltage range (2V to 6V) and extended operating temperature range (-40°C to 105°C), making it compatible with a broader set of system designs. When the original part is unavailable or when automotive-grade reliability is required, the TPS62261TDRVRQ1 provides direct functional equivalence with enhanced specifications.

Frequently Asked Questions (FAQ)

Q: Can the TPS62261TDRVRQ1 replace the TPS62562DRVT in all applications?

A: The TPS62261TDRVRQ1 is electrically and mechanically compatible with the TPS62562DRVT for applications operating within the TPS62562DRVT's specified ranges (2.5V to 5.5V input, -40°C to 85°C). The substitute part's extended specifications provide additional margin. Verify that your application does not require specific commercial-grade certifications that exclude automotive-qualified parts.

Q: What are the key differences between these parts?

A: The primary differences are input voltage range (TPS62261TDRVRQ1 extends to 2V minimum and 6V maximum), operating temperature range (TPS62261TDRVRQ1 extends to 105°C maximum), and qualification grade (TPS62261TDRVRQ1 includes AEC-Q100 automotive qualification). All core electrical parameters—output voltage, output current, switching frequency, and synchronous rectification—are identical.

Q: Are both parts available in the same package?

A: Yes. Both the TPS62562DRVT and TPS62261TDRVRQ1 use the 6-WDFN exposed pad package (6-WSON 2x2), ensuring identical PCB footprint and layout compatibility.

Q: What does AEC-Q100 qualification mean?

A: AEC-Q100 is an automotive industry standard qualification that certifies component reliability under automotive operating conditions, including temperature cycling, vibration, and humidity stress testing. This qualification is required for automotive applications but is not necessary for commercial or industrial applications.

Q: Can I use the TPS62261TDRVRQ1 in a design originally specified for the TPS62562DRVT?

A: Yes. The TPS62261TDRVRQ1 meets or exceeds all electrical and mechanical specifications of the TPS62562DRVT. No design changes are required for direct substitution within the original part's operating envelope.
