LM25149-Q1: FB pin of secondary LM25149

Part Number: LM25149-Q1
Other Parts Discussed in Thread: LM25149,

Hi team,

I plan to use LM25149 in dual phase operation and control the PFM and FPWM from external MCU GPIO.

Is it possible to pull up secondary LM25149-Q1 to VDDA of the primary LM25149-Q1?

I would like to control PFM/SYN of primary controller and FB of secondary controller from 1 GPIO and connect to VDDA of primary controller.

regards.
