Renowned for integrating magnetics and control circuitry into ultra-compact modules, Altera’s solutions set industry benchmarks for power density and thermal performance. Their designs undergo rigorous validation for mission-critical applications, ensuring long-term stability under extreme operating conditions.

Altera’s Enpirion® portfolio specifically addresses noise-sensitive digital loads, combining switching efficiency with low EMI signature. This engineering focus makes them the preferred choice for aerospace, medical, and communications equipment where power integrity directly impacts system reliability. PCX is proud to support legacy Altera designs with authentic components.

About Non-Isolated PoL DC-DC Converters

Non-isolated Point-of-Load converters deliver precisely regulated voltage directly to high-current ICs like CPUs, GPUs, and FPGAs. By positioning power conversion near the load, PoL modules minimize voltage drop, reduce PCB noise, and improve transient response compared to centralized power supplies. This approach is critical for high-speed digital systems where clean power directly impacts signal integrity and processing stability.

Modern PoL modules like the EN6363QI integrate controllers, MOSFETs, and inductors into single-chip packages, eliminating discrete component design complexities. Their high switching frequencies (typically >1MHz) enable smaller external capacitors while maintaining tight voltage tolerance (±1-2%). This makes them indispensable for space-constrained, power-dense applications across industrial automation and embedded computing.

Frequently Asked Questions

Q: Is this part still recommended for new designs?
A: As an obsolete part, the EN6363QI is not recommended for new designs. It remains available for legacy system maintenance or direct replacements.

Q: What are the key differences between isolated and non-isolated converters?
A: Non-isolated converters (like this module) share a common ground between input/output, offering higher efficiency and smaller size. Isolated converters provide electrical separation for safety in high-voltage applications.

Q: Can I adjust the output voltage?
A: Yes, the output is adjustable from 0.75V to 6.12V via external resistors. Consult the datasheet on PCXCo.com for configuration details.

Q: How does remote On/Off functionality work?
A: The active-high enable pin (EN) allows logic-level control (typically 1.8V/3.3V) to power-cycle the module without disconnecting input voltage.

Q: What thermal management is required?
A: The module’s PowerBFQFN package features an exposed thermal pad. Follow layout guidelines in the datasheet for PCB heatsinking. No external heatsink is required below 6A in ambient temperatures ≤85°C.

Q: Does PCX provide lifecycle support for obsolete components?
A: Yes, PCX specializes in sourcing end-of-life and hard-to-find components. Our inventory includes legacy Altera parts with full traceability guarantees.
