In the camera flash applications, in addition using the NCP5005 and CAT4134 these inductive boost type drivers, you can also use NCP5680 and CAT3224 these charge pump type drivers , to support high-megapixels camera flash, and replace xenon flash, match with slim design . Which, NCP5680 and CAT3224 are super capacitor-based LED driver, respectively provide 10A and 4A big flash current. In fact, current 5-megapixel or higher resolution camera is for taking photos in low light high resolution, require high brightness flash. Current white LED light can provide luminous energy of this level, but need energy which is more than 400% of that the camera battery can provide. For example as Semiconductor NCP5680, the device is matched with battery to manage a super-capacitor for driving the LED flash to full brightness, offer up to 10 A large peak current. The integrated driver in NCP5680 also manages the super capacitor, to handle other peak-power functions ,such as zoom, auto focus, audio, video, wireless, GPS data acquisition and radio frequency (RF) amplification, extended battery life and not give up the slim-type design. NCP5680 integrates a super-capacitor, inrush current management and all circuits required by LED current control, saving design staff’s development time, board space and component cost. CAT3224 is the industrial first 4 A single-chip super capacitor LED driver (see Figure 1), integrated dual-mode 1x/2x charge pump, provides three key features: precision super capacitor charge control, discharge current to the LED flash management , as well as to provide constant current for LED flashlight mode. These three modes of current work can use three external resistors as easy programming, can absorb up to 4 A of the LED flash pulse. Super-capacitor peak current technology strengths, is combined with the CAT3224 simple parallel logic interface, to make this device become an excellent application choice of using LED instead of alternative to xenon lamps. |
