The high powered white LEDs available today for use as camera flash lights require up to 2A through the LED to achieve full light intensity. This requires the battery to provide as much as 3.5A for up ...
Addressing demanding compact imaging applications such as in 2+ Mpixel-resolution camera phones, the supercapacitor-based BriteFlash reference design power architecture delivers the pulse power to ...
Parallel LED drivers can be used to create the fast, square, high-current waveforms required for automated image processing. And it’s possible to extend such waveforms to higher currents by connecting ...
