摘要
论述了用低压差稳压器TPS7133和脉宽调制器TL5001A实现TMS320C6000DSP双电源供电方案的设计,给出了电路原理图。该设计方案满足了DSP内核和I/O单独供电的要求和正确的上电顺序。系统成本低,延时短,开关速度快,输出电压精度高。
The article discusses the design method of dual power supply solutions for TMS320C6000DSPs with a low-dropout voltage regulator TPS7133and PWM controller TL5001A.It gives out a principle circuit diagram and testing results.This design satis-fies requirements for powering this DSP core and I /O,and has correct start-up se-quence.This system cost lower,delay times shorter,switching speed faster,output volt-age accuracy higher.
