## Summary description

The BENEDICT R-78K3.3-0.5 is a compact DC/DC converter delivering a fixed 3.3 V output at up to 0.5 A (1.65 W). Designed for board-level power regulation, it provides a regulated low-voltage supply for microcontrollers, sensors and small electronic modules. Use it to step down higher DC voltages to stable 3.3 V in embedded systems, industrial controls and prototype electronics.

## Long description

The BENEDICT R-78K3.3-0.5 is a compact board-mount DC/DC converter that provides a fixed 3.3 V output at up to 0.5 A (1.65 W). Intended for board-level power regulation, the module converts higher DC input voltages to a stable low-voltage supply suitable for microcontrollers, sensors and other small electronic modules. Its small footprint and fixed-output design make it suitable for embedded systems, prototype electronics and industrial control circuits where a reliable 3.3 V source is required.
Advantages
This DC/DC converter offers regulated 3.3 V output with low heat dissipation compared to linear regulators, improving overall system efficiency. The fixed-output topology simplifies integration on PCB designs and eliminates the need for external adjustment components. Its compact size and standardized pinout support easy replacement or retrofitting in existing designs. The converter includes internal protection features typical for switching regulators, contributing to stable operation under varying input conditions.
Suitable for
 Powering microcontrollers and logic circuits that require a stable 3.3 V supply
 Supplying sensors, communication modules and low-power peripherals
 Embedded systems, development boards and prototype electronics
 Industrial control circuits and instrumentation with modest current needs
Key specifications
 Output voltage: 3.3 V fixed
 Maximum output current: 0.5 A
 Maximum output power: 1.65 W
 Form factor: compact board-mount converter
 Regulation type: switching DC/DC converter (step-down)
How to use
Connect the input pins to a suitable higher DC voltage source within the converter's supported input range and attach the output pins to the 3.3 V rail of the target circuitry. Observe correct polarity on input and output connections and ensure adequate copper area or small heatsinking on the PCB if the module operates near its maximum current to aid thermal dissipation. Place decoupling capacitors on the load side as recommended for the powered devices to minimize noise and maintain stable operation.
Usage recommendations
Verify the converter's supported input voltage range and efficiency at your expected load before final integration. Keep sensitive analog or RF circuits physically separated from the switching converter and use proper layout practices—short input/output traces, common ground plane and recommended filtering—to reduce conducted and radiated interference.
