DC-DC converter mean well DETN02L-12 2 W, input 4.5–5.5 V, output 80 mA, 10.9×15.2×7.1 mm

Mean Well DETN02L-12 is a compact DC-DC converter designed for low-power voltage conversion in space-constrained electronics. The module accepts a DC input voltage range of 4.5–5.5 V and provides regulated output capable of delivering up to 80 mA with a total power rating of 2 W. Its small footprint (10.9 × 15.2 × 7.1 mm) allows straightforward integration into embedded systems, portable devices, and other applications requiring stable low-current supply from a 5 V source.

Advantages

The converter combines a small mechanical profile with reliable regulation suitable for continuous operation at low currents. Its wide input tolerance around nominal 5 V ensures compatibility with typical USB and battery-powered systems. Low-power dissipation and compact dimensions simplify placement on dense PCBs or inside compact enclosures while minimizing impact on surrounding components.

How to use

Install the converter on the PCB according to the manufacturer’s recommended footprint and ensure correct polarity of the input and output connections. Provide a stable 4.5–5.5 V DC input and verify that the required load current does not exceed 80 mA. Allow for adequate thermal clearance around the module; although designed for low-power applications, ensure that nearby heat-sensitive components are not adversely affected. Test the output under expected operating conditions to confirm stable regulation before full system integration.

Usage recommendations

Use this converter where small size and regulated low-current output are required. Maintain input voltage within the specified range, avoid continuous loads near the maximum rating without verifying thermal performance, and follow good PCB layout practices—short traces for input/output and appropriate decoupling close to the converter—to ensure reliable operation.
