6.5 Line Transient
Typical Performance Data www.ti.com
A line transient test was conducted with an ac source on the reference design. The line was varied from
230 V
RMS
to 115 V
RMS
to 230 V
RMS
and the transient response was evaluated in each case. From the
oscilloscope image in Figure 19 , it can be observed that the output recovered from line transients within
300ms at full load.
