TPS543B20: adjust output voltage with current DAC injects on FB pin(RSP pin)

Part Number: TPS543B20

Hello expert,

Customer wants to use TPS543B20 to achieve adjustable Vout application. They want to know if they can use current DAC to inject current on FB pin and they want to confirm if this way is workable. And also they would like to know how to adjust voltage from 0.6V to over 1.1V since voltage over 1.1V need to use resistor and under 1.1V need to use VSEL. Thanks a lot!

Best regards,

Ann Lien
