Note:
Please be careful about the thermal conditions during use, like operating current, PCB conditions, ambient temperature,
etc.
This IC may be broken if it is soldered at wrongly rotated position because high voltage is applied to low voltage part.
Please be sure that 1PIN position and PCB pattern is correct before soldering process.
