Splet22. jun. 2014 · To switch it off rapidly, you need 2 transistors in push-pull configuration, PNP+NPN or N-MOSFET + P-MOSFET, so that in 'off' state LED will be shorted to ground. … SpletSo this simple circuit is driving the LEDs at 500mA, suitable for high-powered LEDs. The next step is to calculate the power dissipation: P=I^2 * R = 0.5^2 * 4 = P = 1W. Dissipating 1W is a lot for a single resistor, and requires a 2512 sized or larger surface mount resistor.
