White LED Driver
With PWM Brightness Control
for up to 11 LEDs in Series
BD60A00NUX
BD60A60NUX
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.
