请教各位,lmr14050手册中描述的输出电容由于充放电引起的纹波计算公式,应该是由i=C*du/dt公式转换而来。 参考网络一文章,通过对i=C*du/dt积分,积分区间的选取为何是t off/2至 t on/2 呢?

  • HK32F030C8主频无法超过36MHz

    原先使用的STM32030C8,代码也是用STM的时标准库写的,直接换航顺的HK32F030C8上去,程序运行到时钟配置时不行了。时钟配置代码: static void RCC_Configuration(void) { u16 i; RCC_DeInit(); /*使能HSI */ RCC_HSICmd(ENABLE); /*设置PLL时钟源及倍频系数*/ RCC_PLLConfig(RCC_PLLSource_HSI_Div2, RCC_PLLMul_12); //16MHz(RCC_PLLMul_4),36MHz(RCC_PLLMul_9),48MHz(RCC_PLLMul_12)。 /*使能PLL */ RCC_PLLCmd(ENABLE); i = 1000; while((RCC_GetFlagStatus(RCC_FLAG_PLLRDY) == RESET) && (--i > 0)); /*设置系统时钟(SYSCLK) */ RCC_SYSCLKConfig(RCC_SYSCLKSource_PLLCLK); SystemCoreClockUpdate(); } 将RCC_PLLMul_12改为RCC_PLLMul_9或以下时,程序运行正常。RCC_PLLMul_10及以上时程序就不行了。

  • LM 2587 这种升压模块可以并联使用吗?

    LM2587的输入很宽。如果我嫌功率不够,并联使用,行吗? 是芯片级的并联还是模块级的并联呢?会互相干扰吗? 因为它从 5V 到 12V之后的典型输出是 1.2A,对我还是有点小。 我要的是至少 2A,最好 4A。不过我这个是间歇的,周期1S,占空比一半。它的应该是连续的。 谢谢! [attach]1518850[/attach]
