Circuit driver led 3w

the formula is: LED current in amps = / R3 so for a current of mA, set R3 to ohms you'll need a power resistor usually, R3 power in watts = / R3 this circuit also has the drawback that the only way to use it with a micro-controller or PWM is to turn the entire thing on and off with a power FET. and the only way to change the LED brightness is to change R3, so Estimated Reading Time: 10 mins.  · As indicated in the diagram, ohms will pass about 1 amp maximum current which becomes suitable for driving a 3 watt led safely, and if a 5 watt LED needs to be driven safely, this resistor must be replaced with a Ohms, which will allow a Reviews: 99 ($/count) Get it as soon as Thu, Nov FREE Shipping by Amazon.

This is a very efficient driver for the 3 watt star LED bulbs. The input voltage conncts to the pins and the wires connect to the LED red to anode and white to cathode. It is a constant current supply which puts out milliamps. This driver runs in switching mode at about Khz, so there is some noise. led driver circuit 3w have thousands of hours of service life, extending up to many years. They are handy for protection against short circuit, overload, and overvoltage. They have a hiccup mode and an auto-recovery mechanism to ensure no damage to the circuit. 5 Easy 1 Watt Led Driver Circuits Homemade Circuit Projects. Voltage Multiplier For Power Led Driver.
