The CXLE88129 is a large-current charge pump designed specifically for white LEDs used in camera flash applications. Only one small bucket capacitor is required to develop the output drive, providing a low EMI solution compared with inductive boost regulators. The CXLE88129 has two operation modes: Flash mode and Movie mode. In Flash mode, the CXLE88129 is capable of delivering up to 1A. A safety timer is also included to ensure the LED can not be on indefinitely and overheat.
