Product information

Description

MEAN WELL LDD-350L is a DC-DC step-down constant-current (CC) LED driver designed for compact LED lighting applications. It accepts a 9–36 V DC input and provides a regulated 0.35 A output with a maximum output voltage of 32 V, delivering up to 11 W of output power. The module is a PCB through-hole type with small dimensions (9.9 × 22.6 × 8.9 mm) and an extended operating temperature range from -40 °C to 85 °C.

Advantages

The LDD-350L offers stable constant-current regulation for LEDs and high conversion efficiency in a small PCB-mounted package. It supports PWM dimming and remote ON/OFF control for flexible brightness management, and its wide input voltage range and broad operating temperature make it suitable for varied environments.

Suitable for

  • Small LED lighting modules and strips
  • Embedded lighting in equipment and instruments
  • Battery-powered or vehicle lighting systems with 9–36 V sources
  • Applications requiring PWM dimming or remote on/off control

  • Manufacturer: MEAN WELL
  • Model: LDD-350L (MPN: LDD-350L, EAN: 4021087005234)
  • Type: DC-DC step-down LED driver, constant current
  • Input voltage: 9–36 V DC
  • Output current: 0.35 A (constant current)
  • Maximum output voltage: 32 V DC
  • Maximum output power: 11 W
  • Mounting: PCB through-hole
  • Dimming: PWM dimming supported; remote ON/OFF
  • Operating temperature: -40 °C to 85 °C
  • Dimensions (W×D×H): 9.9 × 22.6 × 8.9 mm

How to use

Install the LDD-350L on the PCB using the through-hole leads and ensure correct polarity for input and output connections. Supply a DC input between 9 and 36 V and connect the LED load to the output, observing the 0.35 A constant-current limit and the 32 V maximum output voltage. For dimming, apply a PWM signal to the dimming/control pin according to the manufacturer's recommended levels; use the remote ON/OFF control input to enable or disable output as needed. Ensure adequate PCB layout and thermal conditions per MEAN WELL guidelines.

Usage recommendations

Use the driver within its specified input range and ambient temperature limits, provide proper cooling and PCB copper area for heat dissipation, and follow MEAN WELL application notes for PWM dimming and wiring to ensure reliable long-term operation.
