-down the input voltage and regulating a constant LED current. The constant current regulation is especially beneficial for LED color accuracy and longer lifetime. The TLD5085EJ also has a PWM input which can be used for LED dimming. The switching frequency of 370kHz allows to use small and inexpensive passive components. An Enable function is implemented to reduce the shut-down current consumption to typ. 0.1µA. This IC is suited for use in the harsh automotive environments and provides protection functions such as current limitation and overtemperature shutdown. The integrated soft-start fea.
