Use of IC Buck-Boost drivers in automotive LED lighting projects Answered
I've been contemplating the use of high power amber or yellow LEDs in a low cost automotive warning system (think tow truck). However, car electrical systems are not set at 12v. They can range from 9 to 19v with spikes up to 70v.
To protect the components I would need more than just a current limiting resister. Under those conditions they would need a buck-boost driver. Unfortunately I'm new to ICs/power LEDa and not sure where to start.
I was hoping someone would be able to help me out with further guidance. I
