BM531Q11 Datasheet White LED Driver

Manufacturer: ROHM

General Description

BM531Q11 is a high efficiency driver for white LEDs and designed for large LCDs.

BM531Q11 is built-in a quasi-resonant control method DCDC converter that employ an array of LEDs as the light source.

BM531Q11 is built-in 250V MOSFET and owing to the external current setting resistance, a power supply design with a high degree of freedom can be achieved.
