BD183x7EFV and Competitors
Although competitor devices can drive only three LED channels, this new ROHM device
can drive four LED channels. This is a tremendous advantage for cost and space
concerns. This driver can also drive one LED string per output channel or drive one string
with two, three, or four output channels, providing design flexibility.
Individual channel control means that advanced lighting techniques such as dimming,
fading, or directional indications are made possible. Competitor devices do not typically
enable individual control of the LED channels, instead only driving all channels with one
control pulse-width modulation (PWM).
