BD60A00NUX
White LED Driver With PWM Brightness Control for up to 11 LEDs in Series

This IC is boost DC/DC converter that can drive white LED with constant current. More stabled white LED lighting can be achieved by direct current connection without electric tolerance and High-speed response by current mode. Moreover, separating IC power supply (2.7V to 5.5V) and coil power supply (2.3V to 20V) makes it possible to widen input range, which will be helpful to be applied to various kinds of applications. Over voltage setting can be selected corresponding to the number of LED lightings. BD60A00NUX is for max 11 lightings, BD60A60NUX is for max 6 lightings.
