SLUSBQ6 – OCTOBER 2013

The linear regulator in Figure 11 generates a current sense RMS voltage of 2.44 V. The linear regulator RMS

current is equal to the input current drawn from the AC line. For example, for a 16-W input power system the

input current should be approximately 0.07 A and a 34.8-
