Once the low input voltage malfunction prevention circuit is enabled, the S.C.P. pin voltage is discharged to about
30 mV but the latch circuit is not reset unless the power is turned off.

When the power supply is started, the output appears to be shorted. The error amplifier output goes to the high
state, the S.C.P. pin voltage, V
PE
, is released, and charging starts. The external capacitor value must be set so that DC-
DC converter voltage output starts before the latch circuit in the later stage is set. If the soft start function is used,
special care is required to assure that the start time does not become excessive.
