## Summary description

The MEAN WELL LDD-300L is a reliable LED driver with an output power of 10W. It operates within a temperature range of -40 to 85 °C and supports an AC input voltage of 9 to 36 V. The output current is 0.3 A with a maximum output voltage of 32 V. Its compact dimensions (9.9 mm width, 22.6 mm depth, 8.9 mm height) make it suitable for various applications, ensuring efficient performance and durability.

## Long description

The MEAN WELL LDD-300L is a DC-DC step-down constant-current (CC) LED driver designed for compact installations. It accepts a 9–36 V DC input and delivers a fixed output current of 0.3 A with a maximum output voltage up to 32 V, providing up to 10 W of output power. The driver is built for through-hole PCB mounting and operates over a wide temperature range from -40 °C to 85 °C.
Advantages
The LDD-300L offers stable constant-current regulation in a compact form factor suitable for space-constrained designs. It supports PWM dimming and remote ON/OFF control, enabling flexible brightness control and system integration. Its wide input voltage range and wide operating temperature make it suitable for a variety of environments.
Suitable for
PCB-mounted LED modules
Low-power strip and accent lighting (up to 10 W)
Applications requiring PWM dimming or remote ON/OFF

How to use
Mount the LDD-300L into the PCB through-hole footprint designed for its dimensions and ensure correct polarity for the 9–36 V DC input. Connect the LED load to the output, making sure the LED forward voltage does not exceed the maximum output voltage. Use the PWM input for dimming control and the remote ON/OFF pins to enable or disable the output as part of a control circuit. Observe proper soldering and cooling practices to maintain reliable operation within the specified temperature range.
Usage recommendations
Use the LDD-300L with LED loads whose combined forward voltage is below 32 V and within the 0.3 A current limit. Allow sufficient PCB copper area for heat dissipation, follow manufacturer guidelines for PWM frequency and wiring for remote ON/OFF, and avoid exposing the driver to temperatures beyond the specified -40 to 85 °C range.
