Hello everyone!
I have been researching and experimenting with making a step-up booster circuit. So far I made the SparkFun 3.3V Step-Up Breakout - NCP1402 (as seen in the picture). It works with one AA or two AA batteries, but just outputs around 3V instead of 3.3V. Not sure what the problem is.
I have mounted a 1W power led on it, but it gets hot without a heatsink (not ideal for my use). Before I did test it with a 5050 SMD LED, but it was not bright enough.
Ideally I would like to have a circuit that outputs a fixed voltage (3.3V) with a variable input (1.5V - 6V) and this all with a really bright LED.
____________________________________________________
I would really appreciate some advice on how to make a step-up/step-down booster and what kind of LED would be smart to use for a flashlight.
- Step up/step down booster
- fixed output at 3.3V
- input range 1.5V - 6V
Thank you!
