About LTC3769 typical application schematic

Hi,

good day!

I have a question of PIN CONFIGURATION in the LTC3760 datasheet, at page 32 -Figure 14. High Efficiency 48V/2.5A Boost Converter

What does this pin (PGND) mean? 

I see the EVB schematic has SGND and PGND in QFN package.

What pin are SGND and PGND in TSOP package ? 

if the 100K ohm should be use, how do we connect it other side ?  Is there any consideration?

Regards,

Mars



add the EVB schematic
