Charge Pump Flash Led Driver With Safety Timer - Semtech Corporation

The SC617 is a high-current Charge Pump designed spe- cifically for use with white LEDs used in camera Flash applications. Only two small bucket capacitors are required to develop the output drive, providing a low EMI solution compared to inductive boost Regulators The SC617 has two modes of operation: l ash mode and spotlight mode. In l ash mode, the SC617 is capable of delivering 500mA of regulated current for a duration of 500ms or up to 700mA for a reduced duration. A safety Timer is also included to ensure the LED cannot be left on indei nitely and overheat. In spotlight mode the SC617 outputs 30% of the l ash mode current and CAN remain enabled continuously.
