Analogictech three mode charge pump IC for white LED

America analogictech Technology Co. Ltd. (AnalogicTech) before the launch of a high output, high output current charge pump IC, suitable for white LED flash. AAT3172 can provide up to 600mA of output current. Each LED channel can be set by a single GPIO through the Analogic AS2C (Advanced simple serial control) wire output 32.

AAT3172 as a three mode charge pump IC, has a load switch (1x), fractional (1.5x) and a doubling (2x) function, so that the internal induction circuit in line with the requirements of LED. 1X and 1.5x mode can reduce the current, suitable for flashlight or theater lighting, this mode is more time than flash mode. The IC dual current mechanism allows the use of single or two (cathode separation) flash LED configurations.
