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 VIN (DC) is input at the timing of Figure 11 and 12.

Therefore, overcurrent protection circuit will operate, and audio frequency noise from coil may generate.

Please turn on ON/OFF or VCC after VIN(DC) to avoid this.
