Heat Sink Enhancement

The smaller layout, though useful for PCB space savings, is also prone to heat sink area

reduction. To enhance the cooling capacity for the VIPer12, mounting a small heat sink directly

in the holes with the 4 DRAIN pins in the VIPer12’s DIP package is recommended (see

Figure 5).
