Figure 9. Soft-start phase
The CSS value is chosen according to equation (1)
CSS = SSGAIN∙ISSCH∙TSS
VFB  =  3∙4μA∙TSS
0.85V
(1)
where TSS is the soft-start time, ISS CH the charging current and VFB the reference of the error amplifier.
During normal operation a new soft-start cycle takes place in case of:
• Thermal shutdown event
• UVLO event
• The device is driven in INH mode
The soft-start capacitor is discharged with a 0.6 mA typ. current capability for 1 ms time max. For complete and
proper capacitor discharge in case of fault conditions, a maximum CSS = 67 nF value is suggested.
In case the soft-start should be externally driven by a voltage step (e.g. the signal from ignition switch in
automotive applications), the schematic in Figure 10 can be used.
The secondary output line regulation is defined, similarly to the primary side, as the variation of the secondary
output voltage due to the input voltage change at a specific current.
