Datasheet Summary
LED Drivers for LCD Backlights
1ch Buck Type (Quasi-Resonant Control)
White LED Driver for Large LCD
Included 250V MOSFET
1.1 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.
