LM25149-Q1: VDDA current capacity

Part Number: LM25149-Q1

Hi team,

I would like to control PFM/FPWM mode depends on the system operation mode.

I pull up PFM/SYNC pin to VDDA through 22kohm register for PFM operation,

and pull down to GND through transistor. 

I concern pull VDDA to GND through 22kohm. Is that OK to configure like this?

regards,
