High Efficiency
For LED Backlight 2ch LED Driver IC
BL0200 Series
General Descriptions
BL0200 series are 2ch output LED driver IC for LED
backlight, and it can do dimming to 0.02 % by external
PWM signal.
This IC realizes a high efficiency by the boost
convertor control that absorbs variability on VF.
The product easily achieves high cost-performance
LED drive system with few external components and
enhanced protection functions.
Package
SOP18
