10 Timing Chart Even if power supply and signal at any timing are input, this IC is not destroyed. However, soft start circuit doesn't operate when VI (DC) is input at the timing of Figure and. Therefore, overcurrent protection circuit will operate, and audio frequency noise from coil may generate. Please turn on O/OFF or VCC after VI(DC) to avoid this.
