Driving High-Power White LED Flash in Camera Phones
Supercapacitors with low ESR (Equivalent Series Resistance) and high capacitance are ideal components for use in pulsed-power applications, such as Flash LEDs and GPRS transmitters, in which the load draws large pulses of current. When connected across the supply, they provide much of the energy needed by each load pulse, reducing voltage ripple, instantaneous supply current and extending battery run time.
