Texas Instruments TPS65279VRHH
TPS65279VRHH variants from Texas Instruments
TPS65279VRHH Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: R, T. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Microcontrollers — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained
Ordering Variants
Compare 2 TPS65279VRHH part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|
| TPS65279VRHHR | 4.5-V to 18-V Input, Dual 5-A Synchronous Step-Down Converter with I<sup>2</sup>C interface 36-VQFN -40 to 125 | Texas Instruments | Active | Compliant | In Stock | |
| TPS65279VRHHT | Dual 5A DC/DC Converter, 4.5-18V In, 2-Output, VQFN | Texas Instruments | Active | Compliant | In Stock |

How to Choose the Right TPS65279VRHH Microcontrollers
Match the footprint first
Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.
Electrical headroom
Compare voltage and current columns in the variant table. For TPS65279VRHH, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "TPS65279VRHH" — include the full suffix (e.g. R, T). RFQ with reel/tube preference and required date code.
