NJU6080
CONSTANT CURRENT LED DRIVER with PWM CONTROL
■ GENERAL DESCRIPTION
The NJU6080 is a constant current LED driver with PWM control.
NJU6080 can reduce board density compared with the case composed
discrete because the constant current value can be set with one resistance.
It can contribute to the reliability improvement of the system because it has
an over current protection circuit and thermal shutdown circuit.
The NJU6080 is suited for a LCD back light and toys, etc.
