tps61222

I have the following questions
1. The manual of TPS61222 states that the ISW switch current is limited to 200mA. Does it mean that 200mA is required to make the chip work properly? The results of my tests seem to require that the input current be greater than 200mA
2. Does the quiescent current in the data sheet refer to the current value during normal operation after turning on the MOS transistor?
3. What does the output ILKG_VOUT leakage current 1uA mean?
4. The output of the rectifier circuit is 2.22V, but the current is only 2-3mA. The cascade boost chip cannot work normally. Is it because of the current?
5. Can you recommend some boost chips that require a small input current, thank you

Hi

    200mA只是开关电流限制，只有当输出功率过大导致电流超过200mA就会保护，所以电流小了，没有问题，只是工作在不连续状态。

    静态电流是指输出电流为0时的输入电流消耗。

    ILKG_VOUT时指EN低时，如果输出有电压，会流入Vout的漏电流（芯片此时不工作）

    此芯片可支持低电流2~3mA输出

您好，谢谢您
我还想咨询一下，当输入电流小于200mA, TPS61222可以正常工作吗？

Hi
可以，200mA是电流限制。

你的负载时什么？需要多大电流？
是不是输入电流太小了？
