QX5305 - Boost LED Constant Current Driver
QX5305 is a high efficient boost type LED driver IC.
It is especially suited to drive several high power and high luminance LEDs in series.
QX5305 uses fixed off-time control scheme, and 1MHz switching frequency can be achieved.
QX5305 set the off-time by an external capacitor, the minimum off-time
