Which of the following ADP2441 pins can be left floating?

PGOOD
FREQ
SS/TRK

 

The PGOOD pin can be left floating if not used.

The ADP2441 requires frequency resistor to be set in order to calculate
switching frequency. It is recommended to connect the frequency resistor
between FREQ pin and AGND.

ADP2441 has a default internal soft start feature. If a user leaves the SS/TRK
pin floating then an internal Soft start of 2ms will be activated.
