SP687 Overview
SP687 blocks current flow in the X2 capacitor safety discharge resistors, reducing the power loss to less than 5mW at 230 VAC. When AC voltage is disconnected, SP687 automatically discharges the X2 capacitor by connecting the series discharge resistors. This operation allows total flexibility in the choice of the X2 capacitor to optimize differential mode EMI filtering and reduce inductor costs, with no change in...
