Other Parts Discussed in Thread: TPS2596 Hi
TPS259240 over current limit accuracy圖如下
假設我們設定over limit current為1A
那照這個表中所對應到1A accuracy為30%, 是不是代表我over current limit可能為0.7A~1.3A
Other Parts Discussed in Thread: BQ25890 Hi All,
我们自己做了一板BQ25890,在测试时发现问题,下面是 TI 的 EVM 板测量结果,稳压源输出电压5V,Input Current Limit 是 2A,负载接在 VSYS上,功耗1A,此时充电电流为1A;
下面是我们自记得板子的测量结果;环境没有变化,指示换上了我们自己做的板子。稳压源输出电压5V,但是消耗的电流只有1.368A,负载接在VSYS上,功耗1A,此时充电电流只有450mA;我们的板子输入电流只能到1…
Other Parts Discussed in Thread: LM3466 Hi all,
I'm using LM3466 for current balancing, and I try to add the current limitation circuit as below circuit, but now the current limitation function cannot work.
Circuit Diagram 1:
I select the R4 (48K…
Other Parts Discussed in Thread: TPS54620 Does the minimum of High-side switch current limit and Low-side switch sourcing current limit decide the output inductor peak current?
For example,in TPS54620 datasheet, High-side switch current limit and Low-side…
