I lean adp1048 (ADP1048 600W Power PFC Evaluation Board | Analog Devices) chip. And I can not understand based on documentation - can adp1048 on eval board or without it manage of output voltage (change it by PWM or somehow else)?
Sure, you can do that. You just disable the modulation for PWM settings. Using the PMBus interface, you can change the output voltage by changing the PWM rising edge or falling edge.
Please let me know if I have answered your question.
