DC-DC converters can drive high-power LEDs
CUI
VLD24 DC-DC converters
CUI Europe has announced a line of step-down constant current DC-DC converters that have been designed for driving high-power LEDs.
The VLD24 series has efficiency levels of up to 95 per cent and a wide input range of 5.5V to 36V DC.
The series has two means of LED dimming: PWM digital dimming and analogue dimming control via a trim POT.
The VLD24 is suitable for a wide range of LED applications where precise accuracy and brightness control is needed, including signage, transport, consumer electronics and signalling.
Available output currents include 300, 350, 500, 600, and 700mA with an output voltage range of 2V to 32V DC.
The VLD24 series has an ambient operating temperature range of -40C to +85C at full load in the 300mA and 350mA versions, and -40C to +71C in the 500mA, 600mA and 700mA versions.
Short-circuit protection and on/off control are standard features.
This series is compact, measuring 0.897 x 0.401 x 0.374in in a PCB mount package.
The VLD24 series is available immediately through Digi-Key.
For quantities of more than 500 pieces, contact CUI Europe directly.
