Adjustable LITIX Linear

The TLE 4242 G is an integrated adjustable constant current source driving loads up to 500 mA. The output current level can be adjusted via an external resistor. The IC isdesigned to supply high power LEDs (e.g. Osram Dragon LA W57B) under the severeconditions of automotive applications resulting in constant brightness and extended LEDlifetime. It is provided in the surface mounted PG-TO263-7-1 package. Protection circuitsprevent damage to the device in case of overload, short circuit, reverse polarity andoverheat. The connected LEDs are protected against reverse polarity as well as excessvoltages up to 45 V.The integrated PWM input of the TLE 4242 G permits LED brightness regulation bypulse width modulation. Due to the high input impedance of the PWM input the LITIXTMLinear can be operated as a protected high side switch.
