BD6592MUV

●Description

BD6592MUV 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 40mA. The wide and precision brightness can be controlled by external PWM pulse. BD6592MUV 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

1) High efficiency PWM step-up DC/DC converter (fsw=1MHz), max efficiency 93%

2) High accuracy & good matching (±3%) current drivers 6ch

3) Drive up to 12^*in series, 6 strings in parallel =72 white LEDs (^*white LED Vf=3.5Vmax)

4) Wide input voltage range (2.7V ~ 22V)

5) Rich safety functions

・Over-voltage protection (OVP)

・Over current limit

・External SBD open detect

・Thermal shutdown

6) Small & thin package (VQFN024V4040) 4.0 × 4.0 × 1.0mm

●Applications

All middle size LCD equipments backlight of Notebook PC, portable DVD player, car navigation systems, etc.

●Absolute maximum ratings (Ta=25℃)
