About Texas Instruments

Texas Instruments (TI) is a globally recognized leader in semiconductor design and manufacturing, with over 90 years of innovation in analog and embedded processing technologies. Their power management ICs set industry benchmarks for reliability, efficiency, and thermal performance, backed by rigorous testing standards.

TI’s commitment to quality ensures components like the PTN78060 series meet stringent commercial and industrial requirements. Engineers worldwide trust TI solutions for critical applications, supported by comprehensive design resources and long-term product lifecycle management.

About Non-Isolated PoL DC-DC Converters

Non-isolated point-of-load converters provide localized voltage regulation directly at the load (e.g., processors, ASICs, or memory). Unlike isolated modules, they lack galvanic separation but offer higher efficiency, smaller footprints, and lower cost – making them ideal for single-board systems where input/output ground sharing is acceptable.

These converters minimize voltage drops across PCBs by delivering stable power near high-current components. Their simplicity reduces design complexity while improving thermal management and transient response in space-constrained applications like embedded computing or distributed power architectures.

Frequently Asked Questions

Question: What does “non-isolated” mean for this converter?
Answer: Non-isolated designs share a common ground between input and output, eliminating the need for transformer isolation. This reduces size/cost while maintaining high efficiency.

Question: Can the output voltage be adjusted below 2.5V?
Answer: No, the PTN78060WAH supports a minimum output of 2.5V as specified in its datasheet. For lower voltages, consider TI’s buck regulator alternatives.

Question: Is this module suitable for automotive applications?
Answer: No, this variant is rated for commercial ITE use (-40°C to +85°C). For automotive-grade solutions, inquire about TI’s qualified AEC-Q100 products.

Question: Does PCX provide design support for this DC-DC converter?
Answer: Yes! PCX offers free technical documentation and application guidance. Contact our engineering team for schematic reviews or thermal layout advice.

Question: What is the typical lead time for this part?
Answer: Most orders ship same-day from PCX’s stocked inventory. Expedited shipping options ensure delivery within 1-3 business days.

Question: How does UVLO protection enhance system reliability?
Answer: Under-Voltage Lockout (UVLO) automatically disables the converter if input voltage drops below 7V, preventing unstable operation and potential damage to downstream components.
