TPS54824RNVR Equivalent & Substitute Parts

Part Overview

The TPS54824RNVR is an active buck switching regulator IC from Texas Instruments, part of the SWIFT™ series. It functions as a step-down converter with positive adjustable output, designed for applications requiring regulated power delivery. The device supports 8A output current with input voltage range of 4.5V to 17V and adjustable output from 0.6V to 12V. As an active product with full RoHS3 compliance, the TPS54824RNVR remains in production. Equivalent substitute parts are identified based on matching electrical specifications and mechanical compatibility within the buck regulator category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPS54824RNVR are identified based on the following critical parameters that determine functional equivalence:

• Buck topology with positive adjustable output configuration
• Single output channel
• Input voltage range: 4.5V to 17V minimum compatibility
• Output current rating: 8A
• Synchronous rectification capability
• 18-pin VFQFN package family
• Surface mount technology
• Active product status with current manufacturing support
• RoHS3 compliance

The RTQ2823AGQVF meets these core substitution criteria. While output voltage range differs (0.6V to 5.5V versus 0.6V to 12V), input voltage range, output current, package form factor, and synchronous rectifier functionality align with the TPS54824RNVR specification envelope for buck regulator applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS54824RNVR and RTQ2823AGQVF are active products with RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current applications. Selection between these parts depends on output voltage requirements: the TPS54824RNVR supports output voltages up to 12V, while the RTQ2823AGQVF is limited to 5.5V maximum output. The TPS54824RNVR also operates to 150°C junction temperature versus 125°C for the RTQ2823AGQVF, providing extended thermal headroom in high-temperature environments. Both devices share identical input voltage range, output current capability, and synchronous rectification architecture. Package variants (18-VFQFN versus 18-PowerVFQFN) are mechanically compatible within the 4.6x4.6mm footprint envelope.

Frequently Asked Questions (FAQ)

Q: Can the RTQ2823AGQVF directly replace the TPS54824RNVR in all applications?

A: Direct replacement is possible only in applications where output voltage does not exceed 5.5V. The RTQ2823AGQVF maximum output voltage of 5.5V is lower than the TPS54824RNVR specification of 12V. Verify your design output voltage requirement before substitution.

Q: Are the package footprints identical?

A: Both parts use 18-pin VFQFN packages with 4.6x4.6mm dimensions. The TPS54824RNVR uses 18-VFQFN while the RTQ2823AGQVF uses 18-PowerVFQFN. These variants are mechanically compatible for PCB layout purposes.

Q: What is the temperature operating range difference?

A: The TPS54824RNVR operates from -40°C to 150°C junction temperature, while the RTQ2823AGQVF operates from -40°C to 125°C. Applications requiring operation above 125°C junction temperature require the TPS54824RNVR.

Q: Do both parts support the same input voltage range?

A: Yes. Both the TPS54824RNVR and RTQ2823AGQVF accept input voltage from 4.5V to 17V, providing identical input compatibility.

Q: What is the switching frequency difference?

A: The TPS54824RNVR supports 200kHz to 1.6MHz switching frequency range, while the RTQ2823AGQVF operates at fixed frequencies of 400kHz, 800kHz, or 1.2MHz. Verify frequency requirements for EMI and filtering considerations in your application.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the TPS54824RNVR and RTQ2823AGQVF are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
