About Board-Mount DC-DC Converters
Non-isolated Point-of-Load (PoL) converters like the EN5365QI deliver localized voltage transformation directly to high-current ICs (e.g., processors, FPGAs). By placing regulation near the load, they minimize voltage drop and noise—critical for maintaining signal integrity in high-speed digital systems. These modules replace discrete power designs, reducing development time and BOM complexity.
Modern PoL solutions prioritize energy efficiency and miniaturization without compromising output stability. Their integrated protections safeguard downstream components from electrical faults, making them indispensable in servers, communication hardware, and embedded platforms where power density and reliability are paramount.

Packaging Options
Available in Tape & Reel (TR) for automated assembly or Cut Tape (CT) for prototyping needs. Contact PCX for reel quantities or custom packaging requests.

Frequently Asked Questions
Q: Is this part still usable despite being marked obsolete?
A: Yes, PCX maintains stock of obsolete components for legacy system support. Availability is guaranteed for immediate shipment.

Q: What protections does the OCP/OTP/OVP feature provide?
A: Over-Current (OCP), Over-Temperature (OTP), and Over-Voltage (OVP) Protection automatically shut down the module during fault conditions to prevent damage.

Q: Can the output voltage be adjusted below 0.75V?
A: No, 0.75V is the minimum configurable output. Refer to the datasheet for resistor programming details.

Q: Is an external inductor required?
A: No, the EN5365QI is a fully integrated module with internal magnetics.

Q: What does “Non-Isolated” mean for this converter?
A: Input and output share a common ground, making it suitable for applications where galvanic isolation isn’t required (e.g., single-board systems).
