4-Channel White LED Driver
with Integrated FET for up to 24 LEDs
BD6586MUV
● General Description
BD6586MUV is white LED driver IC with PWM step-up
● Key Specifications
? Operating power supply voltage range: 2.7V to 5.5V
DC/DC converter that can boost max 24V and current
driver that can drive max 25mA. The wide and
precision brightness can be controlled by external
? LED maximum current:
? Quiescent Current:
? Switching frequency:
25mA (Max.)
0.1 μ A (Typ.)
1.0MHz(Typ.)
PWM pulse.
BD6586MUV has very accurate current drivers, and it
? Operating temperature range: -40 ℃ to +85 ℃
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.
