Texas Instruments LM2591HVS
LM2591HVS variants from Texas Instruments
LM2591HVS Overview
What changes between part numbers, and what to check before you lock the BOM — DC DC Switching Regulators.
Key Features
- Footprint / package: TO-263Single package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 3 distinct suffix patternsExamples: 3.3/NOPB, 5.0/NOPB, ADJ/NOPB. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- DC DC Switching Regulators — 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 3 LM2591HVS part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|---|
| LM2591HVS-3.3/NOPB | Package: TO-263 | Operating Supply Voltage: 60V | Min Supply Voltage: 4.5V | Output Voltage: 3.3V | Output Current: 1A | Max Output Current: 1A | Max Input Voltage: 60V | Number of Channels: 1 | TO-263 | Texas Instruments | Active | Compliant | In Stock | |
| LM2591HVS-5.0/NOPB | 5V 1A Step-Down DC/DC Regulator, 60V In, TO-263 | - | Texas Instruments | Active | Compliant | In Stock | |
| LM2591HVS-ADJ/NOPB | Adjustable DC-DC Regulator, 60V In, 1A Out, 173kHz, TO-263 | - | Texas Instruments | Active | Compliant | In Stock |

How to Choose the Right LM2591HVS DC DC Switching Regulators
Match the footprint first
Packages here: TO-263. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For LM2591HVS, 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 "LM2591HVS" — include the full suffix (e.g. 3.3/NOPB, 5.0/NOPB, ADJ/NOPB). RFQ with reel/tube preference and required date code.
