The TL4242EVM demonstrates the TL4242 IC configured to supply programmable constant current <=500mA to LEDs on the output. Texas Instruments TL4242EVM-543 evaluation module contains a TL4242 integrated circuit (IC), supporting passive components and three OSRAM LEDs in series. The purpose of this EVM is to facilitate evaluation of the TL4242 in a typical LED application. The Texas Instruments TL4242EVM-543 evaluation module (EVM) helps designers evaluate the operation and performance of the TL4242. This device is an integrated, adjustable, constant current source, driving loads up to 500mA. The output current can be adjusted via an external resistor. The device is designed to supply high power LEDs under the severe conditions of automotive applications and architectural lighting.
