Direct Current Control - LED Driver

The second video looking into switching current regulation, specifically utilising a comparator with hysteresis on the input, aka: direct current control. After proving the concept we then try using the circuit to power an LED and calculate the efficiency. Finally I do a quick demo of driving a speaker with this circuit, not a good idea but a nice showcase of its responsiveness What happens when: 0:00 Introduction 0:26 What to change from the previous circuit 1:01 The new circuit 2:06 The inductor 3:06 Testing inductor saturation current 7:05 Schematic and explanation of the new circuit 8:19 Constructing the circuit 8:56 Explaining the physical circuit 10:43 Testing with the LED 12:04 Switching waveforms 13:18 Circuit summary 13:40 Can it drive a speaker? 17:40 Conclusion 18:00 Outro Follow me on Instagram to stay up to date on all the latest stuff:   / electrarc240   Donate through PayPal to support more cool projects: https://www.paypal.com/paypalme/elect...
