Datasheet
6-Channel White LED Driver
for up to 72 LEDs
BD6583MUV-A
● General Description
BD6583MUV-A is white LED driver IC with PWM
● Key Specifications
? Operating power supply voltage range: 2.7V to 22.0V
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
? LED Maximum Current:
? Quiescent Current 1:
Quiescent Current 2:
25mA (Max.)
0.6 μ A (Typ.)
4.6 μ A (Typ.)
? Drive up to 12 in series, 6 strings in parallel =72
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.
● Features
? High efficiency PWM step-up DC/DC converter
(fsw=1MHz), max efficiency 93%
? High accuracy & good matching (±3%) current
drivers 6ch
*
white LEDs ( * white LED Vf=3.5Vmax)
? Rich safety functions
? Over-voltage protection (OVP)
? Over current limit
? External SBD open detect
? Operating temperature range: -30 ℃ to +85 ℃
