Channel Control
The channels are turned on and turned off according to the voltage levels at the
CTL, CTL12, CTL3, CTL4, and CTL5 as described in the following table.

Protective Functions
＊
Short circuit protection and timer latch
The comparator for short circuit detection in each channel detects the output
voltage level of the power converter. When the output voltage falls below the
short detection level, there will be a constant bias current charging the external
capacitor C
SCP
that is connected to the CSCP pin until the capacitor voltage level
reaches about 0.7V and the output transistor turned off consequently. The
actuated protection can be reset by restarting the power source.
