Datasheet
White Backlight LED Driver
For Medium to Large LCD Panels
(Switching Regulator Type)
BD8119FM-M
General Description
BD8119FM-M is a white LED driver with the capability
to withstand high input voltage (36V Max).
This driver has 4ch constant-current drivers integrated
in 1-chip. Each channel can draw up to 150mA max for
driving high brightness on LED. A current-mode
buck-boost DC/DC controller is also integrated to
achieve stable operation against unstable car-battery
voltage input. This also removes the constraint of the
number of LEDs in series connection. The brightness
can be controlled by either PWM or VDAC techniques.
