e charge pump designed speThe SC615 is a high-current e cifically for use with h white LEDs used in camera flash S applications. Only two small bucket capacitors are rea t quired to develop the output drive, providing a low EMI a to inductive boost regulators. solution compared D . w The SC615 has two modes of operation: Flash mode w and Spotlight mode. The SC615 is capable of delivering w 500mA of peak current for a duration of 500ms in Flash mode. In Spotlight mode the SC615 outputs 100mA and can remain enabled continuously. A minimum 0.5Ω sense resistor is used to set the current through the LED in both modes. This resistor dissipates up to 0.125W, reducing the power dissipation requirement of the SC615.
