Digital Adjustment of DC-DC Converter Output Voltage in Portable Applications


要約: This tutorial discusses methods for digitally adjusting the output voltage of a DC-DC converter. The digital adjustment methods are with a digital-to-analog converter (DAC), a trim pot (digital potentiometer), and PWM output of a microprocessor. Each method is assessed and several DACs and digital potentiometers presented.
