## Long description

The MEAN WELL LDD-300LW is a compact DC-DC step-down constant current LED driver designed for low-power LED applications. It accepts a wide input range of 9–36 VDC and provides a regulated output current of 0.3 A with an output voltage up to 32 VDC. With a small form factor (9.9 mm × 22.6 mm × 8.9 mm) and an operating temperature range from -40 °C to 85 °C, this module is suitable for installations where space is limited and reliable performance is required.
Advantages
The LDD-300LW offers stable constant-current regulation for LEDs, efficient step-down conversion from 9–36 V input, and a compact footprint that simplifies integration into fixtures and devices. It supports PWM dimming and remote ON/OFF control, enabling flexible brightness control and system integration. The driver is manufactured by MEAN WELL in Taiwan, meeting common industry quality expectations for small DC-DC LED drivers.
Suitable for
Low-power LED strips and modules

How to use
Connect the driver’s input to a DC source within 9–36 V ensuring correct polarity. Wire the output to the LED load so that the LED forward voltage does not exceed the driver’s maximum output voltage. Use the PWM input for brightness control and the remote ON/OFF input to enable or disable the output as required. Secure the module in a location with adequate ventilation and ensure wiring meets local electrical safety standards.
Usage recommendations
For reliable operation, keep ambient temperature within the specified range, avoid placing the module directly on heat-sensitive surfaces, and ensure the LED load is compatible with a 0.3 A constant current source. Use appropriate wiring and fusing when integrating into vehicle or battery-powered systems.
