Webpackage from the high-voltage side to the low-voltage side (Figure 2). Creepage requirements are proportional to the root-mean-square (RMS) value of the working voltage that appears across the isolator according to the system’s operating conditions. In some cases, you may need to increase creepage to meet clearance requirements.
