Note 2) The input voltage from the [CPZ] pin is used in the internal circuit. The [CPZ] pin must not be open even when the
fast Lock Up feature is unused.
For the output destination from the [CPZ] pin, see “P.12 Fig.5 Loop Filter Schematic”. The [SWIN] pin could be
open when the fast Lock Up feature is not used.
Note 3) Power down refers to the state where [PDN1]=[PDN2]=”Low” after power-on.
Note 4) TEST1 to 3 must be connected to ground.
