Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...
To match the brightness and color of multiple LEDs in RGB applications you should drive all LEDs with a constant current. However, some of these driver ICs require the complication of microprocessor ...
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 ...
