Hi there, I am switching 5 LEDs in parallel powered using a 3.7V lipo battery using a single transistor. I have seen LED driver ICs, but when should i use this? Is my current setup sufficient? I am using a lipo fuel gauge to monitor the battery. Cheers

When to use a LED driver?

A quick diagram I just made.

(nb. Don't worry about the "+5V", the chip works down to 3V...)
