(Note 1) VQFN016V3030: Derate by 21.3mW when operating above 25C
PCB size: 70mm x 70mm x 1.6mm when mounted on a 4-layer glass epoxy board (copper foil area: 70mm x 70mm)
Copper foil thickness: Front side and reverse side 70µm be used, 2nd and 3rd 35µm be used.
Caution1: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.
Caution2: Reliability is decreased at junction temperature greater than 125C.
