Part Number: TPS562206
Hello TI Support Team,
Why does the datasheet add a capacitor from pin 3 to GND, while pin 3 is already GND? TPS56220x 4.2V to 17V Input, 2A, Synchronous Buck Converter in SOT563 datasheet (Rev. A) 
Hi Hieu,
Thanks for pointing it out there is a typo, it should be Pin 1.
Regards,
Usha.
