Specification: Topology: Buck Vcc = 4,5-60 V DC I LED = 960 mA (On request 350, 500, 700 mA) Regulation / dimming: - typical 3% output accuracy - soft start capability (just adding cap to PWM in) - high speed PWM 20kHz max - analog 0,7 - 2,5 V Switching freq: 1 MHz max Rsense ratio: 0,15 Ohm / 1 A Dimensions: 25 x 18 x 7 mm Weight: 4,8 gram Over temperature protection Over current protection Future led Driver IS Rev. A VK20X4 i ro~ Note: if PWM is not connected max ILED generated Options: encapsulation, reverse protection, thermal foldback, MCPCB support Futuro -nupr Lighting design

Thermal foldback Application Example Back side: LED driver Connecting back side of LED driver to fixture heatsink will protect LED fixture against overheating thus extending LED life time and provide safe fixture operation even for inappropriate installations. Thermal foldback is temperature of the module is set to ~80°C Front side: LED module thermal connection can be done by appropriate thermo conductive both side tape or glue. Line regulation LED count = 12x Ta=24°C, Rh=61% thermal connection heatsink Futuro Lighting

Analog Dimming example (local) Appropriate for local dimming (Potentiomter close to Driver) Dimming level (%) * soft start capacitor Potentiometer selection: LIN - linear for linear dimming change LOG - logarithmic change, more appropriate for human eye response Literature: http://www.ti.com/lit/ds/symlink/lm385b-2.5.pdf Futuro Lighting

Analog Dimming example (remote) Appropriate for remote dimming (1-10V dimmer) Dimming level (%) M1 soft start capacitor Signal selection: LIN - linear for linear dimming change LOG - logarithmic change, more appropriate for human eye response Futuro Lighting

Specification: Supply voltage 30-60 V DC Power consumption: 1,2 W max Model: Custom for LED Driver 150 Output voltage 0,55 - 2,55 VDC Outut current: 20 mA / channel max Number of dimm steps: 250 Illumination: Front - Side Blue LED End of range indication: blink (Blue) Power-up fade-in duration: 30 sec Setting memory type: EEPROM Dimensions: 85 x 85 x 30 mm Futuro Lighting resign Note: Implemented non isolated buck driver may generate audiable noise, this is regular behaving
