The TL4242 device is an integrated, adjustable, constant-current source that can drive loads up to 500 mA. The output current level can be adjusted through an external resistor. The device is designed to supply high-power LEDs. The TL4242 is provided in the DRJ (WSON) package. Protection circuits prevent damage to the device in case of overload, short circuit, reverse polarity, and overtemperature. The connected LEDs are protected against reverse polarity as well as excess voltages up to 45 V.

The integrated PWM input of the TL4242 permits LED brightness regulation by pulse-width modulation (PWM). Due to the high input impedance of the PWM input, the LED driver can be operated as a protected high-side switch.

The TL4242 is characterized for operation from –40°C to 150°C.
