Hello,
We have an offline LED driver IC which is of the switched linear regulator type. The IC has a thermal pad on it. However, its datasheet does not say to which pin the thermal pad should be connected. If we connect the thermal pad to a bottom layer copper pour on the PCB, then we can’t leave this pad floating. –Because as you know, floating copper pours on PCBs generate all kinds of noise problems?
Do you agree that leaving the copper pour which connects to the thermal pad ‘floating’ will invite all manner of noise problems…specially since on our tiny PCB, this ‘floating’ pad will be near the microcontroller and all the PCB traces leading to the microcontroller.
The LED Driver IC is DT3007B by Seoul semiconductor, and we have requested the datasheet from info.europe@seoulsemicon.com but get no reply. The datasheet is nowhere to be found on the web.
The IC is featured on this app note…
