 CUI Inc announced the addition of a surface mount series to its high efficiency, constant current DC-DC LED driver family. Designed to drive high power LEDs, the VLD25-SMT series provides efficiency levels of up to 96%, current accuracy of ±2%, and an ultra-wide input range of 5.5 to 48 VDC. The series offers two means of LED dimming: PWM digital dimming and analog dimming control via a trim pot, making it ideal for applications where precise accuracy and brightness control is needed, including signage, transport, consumer electronics, and signaling.
The series is compact, measuring 0.94 x 0.54 x 0.30 inches in a 16-pin SMT package. Available output currents include 300, 350, 500, 600, and 700 mA with an output voltage range of 3.3 to 36 VDC. The VLD25-SMT series has an ambient operating temperature range of -40°C to +85°C at full load in the 300 mA and 350 mA versions and -40°C to +71°C in the 500 mA, 600 mA, and 700 mA versions. Short-circuit protection and on/off control are standard features. |
