QX5305 Datasheet (Qxmd) - Boost LED Constant Current Driver

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
