8 15A HTSSOP16 DEMO BOARD DESCRIPTION
A specific Demo Board has been realized for the HTSSOP16 package. The features are the same of the 15A
Demo Board previously described but thermal performance are improved. The PGOOD signal is used as a logic
level and it's been pulled up to VIN because there's no other appropriate voltage available on the demo board.
In case of input voltage higher than 7V (PGOOD Pin Maximum Absolute Rating) a 5V reference is re-
quired.
