Buck-Boost LED Drivers with 4:1 Input Voltage Range

November 04, 2014 by Jeff Shepard

Mean Well Enterprises Co. Ltd. has introduced the LDB-L/LW series of buck-boost dc-dc potted-module constant-current LED drivers. This series offers multiple models of different current levels, including; 300mA/350mA/500mA/600mA. A very wide input/output range is provided. With the built-in EMI filter, LDB-L/LW converters comply with the lighting standard EN55015 without the need for additional external anti-electromagnetic components. Build-in pwm dimming is included and these LED drivers have remote on/off control.

The LDB-L/LW series has an input range of 9- to 36-Vdc and provides constant-current outputs between 2- and 40-Vdc. Typical efficiencies are up to 91%, depending on output ratings and the input voltage. These converters include short-circuit and over-temperature protection. They are delivered in a UL 94V-0 flame retardant plastic case that measures 31.8mm X 20.3mm X 12.2mm. The operating temperature range is -40 to +70 Degrees C.

In addition, the potted design makes it workable in a harsh environment with high dust and high moisture. LDB-L/LW series is recommended to be used for the LED lighting modules, such as street lighting, landscape lighting, tunnel lighting, household lighting, and backlighting.
