摘要
本文制作了以TL494芯片为核心的直流变换直流(DC-DC)稳压电源。该电源实现了输入24V电压,输出12V的降压、稳压功能。同时,该电路还具有短路保护,过流保护功能。其工作稳定、效率高、性能良好,参数指标符合设计的基本要求。
DC-DC voltage-stabilizing power supply, which core is TL494 chip, is made in this paper. The power supply can lower and stabilize voltage that outputs voltage of 12V as input of 24V voltage. At the same time, it has functions of short-circuit protection, over current protection, stability, high effi- ciency and high performance. And the basic parameters comply with requirements of design.
