Hi Team,

Our customer would like to connect “Master1” and “Master2”.

Because, they would like to operate each device using frequency of Master1 and to set other output voltage.

Could you please let us know if you have any concerns about following circuit?

Regards,

Hi Kanemaru,

The circuit is in correct configuration. The Vout2 boost should be in Master2 mode to sync by the Vout1 boost SYNCOUT pin. And the OPT pin needs to be tied to Vcc or some voltage higher than 3V to be configured in Master2 mode.

Best regards,
Xiang
