I am designing a digital camera application and need to find a highly efficient driver. I am new to LED design, can I use a charge pump or do I need to use a traditional boost converter?
Depending on your requirements, you should be able to use a charge pump for this type of application. Try searching the onsemi.com website for the CAT3648 and look to see if it meets your parameters. It can drive up to 4 LEDs.
