9 STK70-0-E Timing Charts The IC will never be subjected to fatal damage when a power supply input or signals are applied or are not applied at any timing. If the IN (DC) input is applied to the IC at the timing shown in Figure 1 or 1, however, since the soft start circuit is inactive in this case, it is likely that the overcurrent protection circuit is activated and audible tone is generated out of the coil. To avoid this area of timing, it is necessary that the ON/OFF or input be applied after IN (DC). Input entry time Input entry time IN (DC) s, ON/OFF ON ON oltage control sig.
