Please see the attached image which shows the circuit of driving LED using an opamp. We are fixing current through LED using opamp. I am clear about how they obtained the current equation.Isense=Vin/Rsense because opamp is in negative feedback
My question is why they are not...

I'm working on a micro controller project to do race timing for rowing regattas. It's coming along pretty nicely and I want to add one component: A finish light that will be turned on and off by the microcontroller.
The light needs to be seen from a distance in sunny conditions. I want...
HI all, I want to understand the proper way to make a dimming function for the XL6005.
I found some schemes that suggest using the EN Pin:
And some that use the FB Pin:
So which one should do the work and what PWM signal should I use?
Saw this thread on the same topic, but it was suggested I start my own, so here goes.
Looking to power my Japanese garden lantern with a 3.85v phone battery...
Hi all, a driver circuit needed for lighting a 30W LED* (one color) -
I had a look at the XL6005 datasheet and wanted to make sure I understand it properly based on the following diagram**:
1. To drive the LED with 300mA I should make RS = 0.73 ohm (ILed=0.22/0.73=0.3A)
2. To limit the max...
Good night. I bought this flashlight for my bike:
But the light that comes out seems very little to me. I think it has more potential. Could I modify...
I'm trying to design an LED driver that takes a ground as ON, performs a logical NOT on it, and sends it into an N Channel MOSFET. The MOSFET will give ground to a color channel on an LED strip.

I believe I have taken care of everything, but to be honest, this is...
