Fonte de alimentação MEAN WELL DETN01L-05 1 W entrada 4,5-5,5 V saída 5 V

The MEAN WELL DETN01L-05 is a compact PCB-mount DC-DC converter designed for low-power applications. It accepts an input voltage between 4.5 and 5.5 Vdc and provides a regulated 5 V output with a total power rating of 1 W. The module is supplied in an SMD package, includes a short-circuit protection feature that responds within about 1 second, and complies with RoHS requirements.

Advantages

The SMD-mounted design allows for space-efficient installation on printed circuit boards. The narrow input voltage range makes it suitable for stable 5 V supply sources such as USB power. Built-in short protection increases reliability in case of output faults. RoHS compliance ensures that the unit meets common environmental and safety restrictions.

Suitable for

• Low-power embedded systems and microcontroller boards
• USB-powered devices and peripherals
• Sensor modules and small instrumentation
• PCB designs requiring a compact 5 V regulator

How to use

Mount the DETN01L-05 on the PCB following the manufacturer’s recommended footprint and soldering guidelines. Connect a stable 4.5–5.5 Vdc source to the input pads and take the regulated 5 V output from the output pads. Ensure the output load does not exceed the unit’s 1 W power rating; if a higher current is required, use a different converter with a suitable power rating. Observe standard ESD handling and thermal considerations during soldering and operation.

Recommendations

Use the converter on PCBs with adequate copper area for heat dissipation, keep the input supply within 4.5–5.5 Vdc, and avoid continuous overloads; rely on the short-circuit protection for fault conditions but design the system to prevent repeated trips.
