Startup sequence
[Example]
The startup sequence of each output terminal can be set using the detection (DET1 to DET4) and control pins (CTL1 to
CTL4). The detection pins switch from L to H when the feedback side INV voltage of each block reaches 80% of the
reference side. For this reason, the startup sequence can be set by connecting a detection pin to the control pin to be
started up next.
The detection pins have a hysteresis width with a standard value of 0.3 V. However, if a ripple exceeding this is applied to
the INV pin, chattering will occur. After all outputs have begun, if even one turns off, all outputs will stop.
