Redefining the sources of power

Gaia Non Isolated DC/DC Converters


Simplifying your future

Non Isolated DC/DC Series

GAIA Converter offers compact, non-isolated DC/DC converters designed for high-efficiency power distribution in space-constrained applications.

With an input voltage capability exceeding 35V, these converters provide low output voltages ideal for use as Point-of-Load (PoL) regulators. They feature advanced functionalities such as sequencing and synchronization, making them suitable for complex power architectures.

Delivering up to 14A at low output voltages and up to 260W at higher voltages, these modules offer wide output adjustability and are optimized to respond to fast load transients—ensuring stable, precise power delivery in dynamic operating conditions.

Protection Functions

Gaïa Converter’s Non-Isolated DC/DC Converters are designed with built-in protection features to ensure reliable and safe operation in mission-critical applications. These advanced protection functions include:

  • Input Undervoltage Lockout (UVLO) – Prevents operation when the input voltage is too low, avoiding unstable performance and potential damage.

  • Output Overvoltage Protection (OVP) – Safeguards connected components by limiting excessive output voltage.

  • Overcurrent Protection (OCP) – Protects the converter and downstream systems by limiting current during overload conditions.

  • Short-Circuit Protection (SCP) – Automatically shuts down the output to prevent permanent damage in case of a short circuit.

These robust protection mechanisms ensure long-term reliability and stability, making Gaïa Converter’s Non-Isolated DC/DC Converters an ideal choice for aerospace, defense, rail, and industrial power systems.
