ROHM BD6150MUV Data Manual
Summary
This advanced LED driver IC is designed for creating consistent, bright white backlighting across medium to large LCD panels. Featuring a high-efficiency PWM step-up DC/DC converter, it ensures precise brightness control and minimizes hotspot artifacts using highly accurate current drivers across multiple strings. The regulator supports wide input voltage ranges (4.2V–26V) and includes comprehensive protection features like over-voltage detection and thermal shutdown. Ideal for engineers developing displays for Notebook PCs, portable AV equipment, and car navigation systems.

BD6150MUV
●Description BD6150MUV is white LED driver IC with PWM step-up DC/DC converter that can boost max 40V and current driver that can drive max 30m A. The wide and precision brightness can be controlled by external PWM pulse. BD6150MUV 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=1.25MHz / 0.75MHz) 2) High accuracy & good matching current drivers (MAX30m A/ch) 3) Integrated 50V power Nch MOSFET 4) Soft start 5) Drive up to 10 in series 6strings in parallel 6) Wide input voltage range (4.2V ~ 26V) 7) Rich safety functions ・Over-voltage protection ・Over current limit ・LED terminal open/short protect ・External SBD open detect / Output short protection ・UVLO ・Thermal shutdown 8) 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℃)
