Step 7 – Selection of PeakSwitch External
Components
Bypass Pin Capacitor
For the BYPASS pin, use a 0.33 µF, 50 V ceramic capacitor or
a 1 µF, 50 V electrolytic, whichever is lower cost.
Step 8 – Selection of Under-Voltage or AC Line Sense
Components
UVLO prevents the supply from starting up prematurely, while
latching shutdown protects the IC, the supply and the load from
fault conditions. The rectified AC input voltage that forces the
current into the EN/UV pin to exceed 25 µA sets the UVLO
threshold.

For example, if regulation is lost due to a short circuit, an open
loop or an output overload condition, and the input voltage is
sufficient to support normal operation (>25 µA into the EN/UV
pin), then PeakSwitch will latch off. To reset the latch, the AC
input has to be removed long enough so that the current into
the EN/UV pin falls below the 25 µA UV threshold. Once
AC is reapplied, the next time the EN/UV pin current exceeds
25 µA, the supply will attempt to restart.
For some applications, the time for the EN/UV pin current to
fall below 25 µA may be excessive due to the time for the bulk
input capacitor to discharge. In such cases, a fast AC reset circuit
can be used allowing latching shutdown to be independent of
the load and voltage on the bulk input capacitor. This prevents
