Part Number: UC3825 3825手册上写Ilim引脚门槛电压是1V
现在做一个同步boost，模拟控制用运放比较器做的，但是启动过程中电感电流上存在一个启动冲击电流，现在想换用3825来做控制，看了下3825带pulse by pulse current limit，那这个功能能否在启动中限制启动冲击电流，是否为检测到电流超过门槛，就关闭两个驱动还是关闭其中的一个？麻烦详细说说，谢谢
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…
The BQ25690 plus the current limit switch might work here. In forward mode, the BQ25690 charges the battery from power at VBUS. When VBUS drops below a certain threshold, the BQ25690 backup mode feature can be armed to automatically operate in reverse…
