... ILD2035 incorporates a temperature protection circuit referring to the junction temperature of the IC. The higher the junction temperature the lower the current of the LEDs. This feature helps to reduce the power dissipation of ILD2035 and the LEDs. Yet still the product specific maximum ratings for the junction temperature need to be observed to avoid a permanent damage of the devices. ...
