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. SpletDue to the very high level of saturated switching, the pulse width broadens from about 20 ns to 40 ns. The output pulse is also more symmetrical than the input pulse: To verify the high emitted optical power from the LED under a drive current of 800 mA, the detector with an active area diameter of 1mm was moved 35 mm from the LED emitting source.

SpletThe design consists of four principle elements: inductor, power switch (MOSFET, IGBT, or similar), diode, and capacitor. When the switch is closed the circuit is ON and the inductor experiences increased current flow and stores energy in its magnetic field. For all intents and purposes there is no current flow in the diode and the capacitor.

SpletA curve-tracercapable of the 1A+ currents used by high power LEDs can be used to draw the I-V characteristic of an LED. If the curve tracer is capable of high current and high voltage, it can also be used to draw the complete I-Vcurve of the entire LED array. Total rD can determined using the tangent-line method from that plot.
