| Abstract: | Aim To design the double symmetric power supply solution based on TI power management IC. Methods 2 pieces of MC33063,one for DC-DC step-down controller and the other for the inverting controller,are used.The resistance voltage divider is set to gain the required output voltage.The periphery discrete component values are calculated to lower down the ripple voltage and voltage variation.So the double symmetric power supply is achieved. Results The double symmetric power supply features stability,reliability,... |
