in applications with and without an external resistor (2 M
)
connected to the EN/UV pin.
During power-down, when an external resistor is used, the
power MOSFET will switch for 50 ms after the output loses
regulation. The power MOSFET will then remain off without
any glitches since the under-voltage function prohibits restart
when the line voltage is low.
Figure 12 illustrates a typical power-down timing waveform of
TinySwitch-II
. Figure 13 illustrates a very slow power-down
timing waveform of
TinySwitch-II
as in standby applications.
The external resistor (2 M
) is connected to the EN/UV pin in
this case to prevent unwanted restarts.
