About Non-Isolated PoL Modules

Non-isolated point-of-load converters deliver regulated voltage directly to high-current loads like processors or memory without galvanic isolation. They excel in space-sensitive designs by minimizing component count and PCB area while enabling precise voltage control near the load, reducing losses from trace resistance and improving transient response.

Essential in modern electronics, PoL modules simplify power architecture in multi-rail systems. They support dynamic voltage scaling for energy efficiency and integrate protections to prevent damage from faults. PCX stocks a wide range of PoL solutions for prototyping and production.

Packaging Options

Available in Tape & Reel (TR) for automated assembly or Cut Tape (CT) for prototyping needs.

Frequently Asked Questions

Q: Is the EN6347QI suitable for industrial environments?
A: Yes, it operates reliably from -40°C to 85°C, making it fit for industrial and commercial systems.

Q: Can the output voltage be adjusted?
A: Absolutely. The output is programmable from 0.6V to 6.24V via external resistors.

Q: Does it require external cooling?
A: Typically not, thanks to 95% efficiency and the thermal pad design. Ensure adequate PCB copper pour for heat dissipation.

Q: Why choose a non-isolated PoL converter?
A: Non-isolated modules offer higher efficiency and smaller size than isolated alternatives when input/output ground separation isn’t required.

Q: What does “Obsolete” status mean for this part?
A: Altera has discontinued production, but PCX maintains stock for legacy designs. Contact us for lifecycle support alternatives.

Q: How do I enable/disable the output?
A: Use the “Enable” pin (Active High logic)—pull high to activate or low to shut down.
