350ma Constant Current Led Driver Circuit

Demonstration circuit 762 is a 350ma 1w synchronous boost white led driver featuring the ltc3490 and a lumileds luxeon led.

350ma constant current led driver circuit.

So if you want to connect one or more luxeon 1w leds which has a power consumption of 350ma the calculation should look like this. 1 25 the constant reference voltage of the lm317 divided by 0 350 the leds power consumption makes 3 57. Use prima transformer driver and or ballast to comply with cul. Designed for indoor application.

In the constant current led driver circuit you do state that in step 6 the input voltage varies from 3 volts right up to 60 volts. Output 350ma 6 1 8w 3 36v. So if the resistor is 3 57 constant current will be 350ma. Lamps wired in series and total value of led vf should be under 48v.

18w 350ma constant current led driver. Short circuit over load over heat and auto recovery mode. Mean well s ap constant current driver is a good example shown below. Screw terminals for easy connection suitable for powering led s requiring constant current supply dimensions.

Question 1 year ago answer upvote. Fly leads 20awg 15cm for rapid connection. A constant current led power supply works by varying the voltage along an electronic circuit and thus allows the current to remain constant throughout the led system. Compact lightweight in plastic case.

The board comes with two aa alkaline battery cells to be stuffed in the battery pack on the back of the pcb. 73 5 x 35 x 23mm universal input r. The input voltage range of the lt3490 is 1v to 3 4v. I need help to make led medical light source.

Is the input voltage dc or ac. Higher current ratings do make the led brighter but if not regulated the led will draw more current than it is rated for. This led constant current power supply has screw terminals on the input and output for easy connection. However the demo board operates with a 1 8v to 3 5v range.
