About Non-Isolated PoL DC-DC Converters

Point-of-Load converters provide localized voltage regulation directly at power-hungry components like CPUs, ASICs, and memory subsystems. Non-isolated variants offer higher efficiency and simpler designs compared to isolated modules by eliminating transformer-based voltage separation. This makes them ideal for cost-sensitive, space-constrained applications sharing a common ground plane.

Modern PoL modules like the EN5366QI integrate controllers, MOSFETs, and passive components into single packages. This “power-on-a-chip” approach simplifies PCB layout, reduces BOM costs, and accelerates time-to-market. They are fundamental in distributed power architectures for servers, networking gear, and high-performance embedded systems requiring precise voltage margining and dynamic response.

Packaging Options

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

Frequently Asked Questions

Q: Is this part still suitable for new designs despite being obsolete?
A: While discontinued by the manufacturer, it remains ideal for legacy system maintenance, repairs, or existing product lifecycles. PCX maintains stock for such critical needs.

Q: What documentation supports this converter?
A: Access the full EN5366QI datasheet hosted on PCXCo.com for schematics, thermal data, and layout guidelines.

Q: Can the output voltage be adjusted?
A: Yes, the output is configurable between 0.75V–3.3V via external resistors as detailed in the datasheet.

Q: Does it require external cooling?
A: The 93% efficiency minimizes heat generation. Forced airflow isn’t required below 6A in most ambient conditions, but thermal vias under the PowerQFN pad are recommended.

Q: What does “Remote On/Off” functionality provide?
A: It enables digital power sequencing via the Enable (Active High) pin, allowing system controllers to activate/deactivate the module.

Q: Are evaluation boards available for this part?
A: PCX can provide guidance on compatible Altera Enpirion® development tools – contact our technical support team for assistance.
