白色背光LED驱动器适用于中小型液晶面板(开关稳压器型) White Backlight LED Drivers for Small to Medium LCD Panels Switching Regulator Type
● General Description
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.
