Setting time constant for Time-latch Short-circuit protection
The SCP comparator detects each channel output voltage while the power converter work at
normal condition. Q1 is turn on, and the voltage level of CSCP pin is held at low level. If the load
of one channel rapidly due to a short of the load, causing the output voltage to drop, the SCP
comparator output on that channel goes to "H" level. The transistor Q1 to be turned off and the
external capacitor C

When the C
SCP
is charged to the 0.7V, the timer-latch is set and output is turn off (dead time is set to 100
). At this point, the timer-latch is closed and the CSCP terminal is held at "L" level. It could be
disabled short circuit protection function by connecting CSCP pin into the ground.
