Hello, i have buck converter IC LM2576HV. Chip's output voltage, according to manufacturers datasheet, can be controlled with potentiometer. My question is: can i control LM2576 output voltage with DAC converter? There is two types of DAC: voltage and current. Also converters may be buffered and without buffering. I have bought MAX531 DAC with parameters: buffered voltage output, power supply is +5v, The MAX531's internal op amp may be configured for a gain of +1 or +2. So can i control converter with this DAC, o i need current DAC?
