PLZ-U Application Operation 5-5
5.3 Switching Function
The switching function operates in CC and CR modes. The PLZ-U switches the pre-
set value (SET value) and the level value at the speci
fi ed switching frequency and
duty cycle.
The switching settings are the switching level, switching frequency, duty cycle, and
slew rate. These settings can be changed even when the load is turned on.
• Switching operation starts after fi ve times the soft start time or 20 ms, whichever
is longer, elapses.
• In the switching operation in CC mode, the power may be limited even if the
ALM indicator does not illuminate.
• In the switching operation in CR mode, the power or current may be limited even
if the ALM indicator does not illuminate.
