CAT4101 Datasheet - ON Semiconductor

CAT4101 1A Constant-Current LED Driver

The CAT4101 is a constant *current sink driving a string of high *brightness LEDs up to 1 A with very low dropout of 0.5 V at full load. It requires no inductor, provides a low noise operation and minimizes the number of components. The LED current is set by an external resistor connec.

CAT4101 Features
