6-Channel White LED Driver
for up to 72 LEDs
BD6583MUV-A
General Description
BD6583MUV-A is white LED driver IC with PWM
step-up DC/DC converter that can boost max 42.5V
and current driver that can drive max 25mA. The wide
and precision brightness can be controlled by external
PWM pulse. BD6583MUV-A has very accurate current
drivers, and it has few current errors between each
strings. So, it will be helpful to reduce brightness spots
on the LCD. Small package type is suited for saving
space.
