Infineon Technologies AG Linear LED Driver IC TLE4309G

The TLE4309 is an integrated adjustable constant current source for driving loads up to 500 mA. The output current level can be adjusted with an external shunt resistor. Supplying high power LEDs with the TLE4309 ensures constant brightness independent from supply voltage or LED forward voltage spread. Therefore, LED lifetime is extended by protecting from overcurrent and overtemperature. The TLE4309G is provided in the surface mounted PG-TO-263 package with excellent thermal resistance.
