Abstract : Design a simple numerical digital DC power supply, including digital control part ,abercrombie ireland, D / A conversion section and the adjustable voltage regulator part. Digital part of the core circuit two cascaded BCD code up / down counter CD40192; its preset input D0 ~ D3 and BCD code dial switch connected to a voltage of the preset function ; order to complete the voltage of the automatic continuous scan ,mac cosmetics wholesale, joined the CD4060, 8HZ pulse frequency generated by the CD4011 and CD4069 as well as composition of the gate ; D / A conversion part , and adjustable regulators ,tory burch outlet, respectively, using a low-cost part of the right to resistance and three-terminal voltage regulator integrated circuit module CW7805 . Using Multisim2001 the entire circuit simulation and testing ,tory burch outlet, by pressing a button on the control of output voltage step value , and key long press time to a continuous increase or decrease or change to a set of direct voltage , output voltage using three digital display . Test results show that the design meets the design requirements , has some practical value.
