led driver

Saw this thread on the same topic, but it was suggested I start my own, so here goes. Former thread: https://forum.allaboutcircuits.com/threads/cd4060b-timer-circuit-design-12-hour-on-off-repeat.156495/page-2#post-1511407 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: https://www.ebay.es/itm/Luces-Bicicleta-Luz-10000LM-Impermeable-3XT6-LED/292872854958?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649 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. LED Strip Driver-schematic.pdf I believe I have taken care of everything, but to be honest, this is...
