NJU6080 Datasheet | New Japan Radio

DESCRIPTION The NJU6080 is a constant current LED driver with PWM control. NJU6080 can reduce board density pared with the case posed 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. - PACKAGE OUTLINE NJU6080F1 - FEATURES - Supply Voltage Range : 2.5V ~ 5.5V - LED Output Current : 100m A ( max. ) - Output Current Accuracy : ± 1.8% - Operating Current : 150µA ( typ. ) - One white LED can be lit. - External Parts : Current limitation resistance - Internal Thermal Overload Protection - Internal Over Current Protection - CMOS Technology - Package Outline : SOT-23-6 - BLOCK DIAGRAM VDD NJU6080 VREF ( 0.2V ) RS Current Limit / Thermal Shut Down Control Logic LED - PIN CONFIGRATION 6 5 4 1 2 3 1.
