TPS61089: Can it be used as a tunable output with external analog signal injected to FB?

Part Number: TPS61089

Hi Expert

As the title, could TPS61089 be used as this way in theory? User case is 5V input, output 8V to 9V tunable.

Thanks!

Hi Yichen,

Do we have any similar ref/design? Not limited to this device.
