Designing Power Supplies Using XDCP Mixed Signal Products for PRIMARY CONTROL

Designing Power Supplies Using XDCP Mixed Signal Products for PRIMARY CONTROL. This Application Note is to illustrate the use of XDCP (Digitally Controlled Potentiometer) in the design of switching power supply. A mixed signal XDCP device is used to set the output voltage, the PWM (Pulse Width Modulation) frequency and the overcurrent limit in a reference design of a 12V@10A power supply. The techniques reflected in this working reference design could be used in the general power supply design for industrial, consumer and communication systems
