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 VDC 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" in a 16-pin SMT package. Available output currents include 300 mA, 350 mA, 500 mA, 600 mA, and 700 mA with an output voltage range of 3.3 VDC 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.
