More Features
* One additional rectifying diode is required for asynchronous converter
Inductor boost converter that extends battery life in flash or video mode, is critical for high performance
camera phone
Driving single and multiple LED allows one inductor boost converter to use across multiple platforms
Having multiple LEDs not only gives Xenon Flash physical resemblance, but driving them by one output
allows inductor boost converter provides more and uniform output light, resulting in high quality picture
