TL4242EVM-543: 0 ~ 500mA @ 41V Max, 4.5 ~ 42V in

Summary

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 TL4242 device is an integrated, adjustable, constant-current source, driving loads up to 500 mA. 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. The TL4242 IC is capable of operating at input voltages up to 42 V. Due to thermal considerations however, the EVM may not allow an input voltage this high.
