Mike DonnellyThis simple "Joule Thief" self-oscillating LED circuit will produce light even when the battery voltage drops to 0.4 V.
Mike DonnellyThis is a companion example to the design: "TDFS Impedance Stability of Transmission Line Fed LED Driver - Switching".
Mike DonnellyThis example demonstrates the use of the TDFS method (Time Domain Frequency Sweep) to measure impedance stability ratio.
Mike DonnellyThis LED Dimmer Circuit uses a 555 Timer to control the PWM duty cycle of the current drive.
077zzThis example demonstrates the use of the TDFS method (Time Domain Frequency Sweep) to measure impedance stability ratio.
bedrosian1134This LED lighting example demonstrates the value of simulating both the electrical and thermal* aspects of power dissipating circuits together, simultaneously.
