LED driver / Constant current source - Nexperia
Our linear constant current LED drivers are a simple and robust solution to drive low- and medium-power LEDs up to 250 mA – making up the vast majority of applications in the growing LED market. The AEC-Q101 qualified NCR devices are easy-to-use, reliable, cost efficient, and do not affect EMC.
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 connected to …
The CAT4016 is a 16 channel constant current driver for LED billboard and other general display applications. LED channel currents are programmed together via an external RSET resistor. Low output voltage operation on the LED channels as low as 0.4 V (for 2 to 100 mA LED current) allows for more power efficient designs.

The TLC5928 is a 16-channel, constant-current sink LED driver. Each channel can be turned on/off by writing serial data to an internal register. The constant-current value of all 16 channels is set by a single external resistor. The TLC5928 has two error detection circuits: one for LED open detection (LOD) and one for a pre-thermal warning (PTW).
The CL6 is a fixed-current linear regulator designed for driving high-brightness LEDs at 100 mA from nominal 12V, 24V and 48V power supplies. With a maximum rating of 90V, it is able to withstand transients without the need for additional transient protection circuitry. The CL6 is offered in both TO-252 (D-PAK) and TO-220 packages.
