Functional Description
3.4 Startup Phase
S oft S tart counter
When the VVCC exceeds the on-threshold voltage, the
IC starts the Soft Start mode (see Figure 10).
The function is realized by an internal Soft Start
resistor, an current sink and a counter. And the
amplitude of the current sink is controlled by the
counter (see Figure 11).

Figure 9 Soft Start
In the Startup Phase, the IC provides a Soft Start
period to control the primary current by means of a duty
cycle limitation. The Soft Start function is a built-in
function and it is controlled by an internal counter.
.
Figure 11 Soft Start Circuit
After the IC is switched on, the VSFOFTS voltage is
controlled such that the voltage is increased step-
wisely (32 steps) with the increase of the counts. The
Soft Start counter would send a signal to the current
sink control in every 600us such that the current sink
decrease gradually and the duty ratio of the gate drive
increases gradually. The Soft Start will be finished in
20ms (tSoft-Start) after the IC is switched on. At the end of
the Soft Start period, the current sink is switched off.
