please share the DS of the transformer to complete the schematic review.
As mentioned above, efficiency and EMI will be a challenge. I recommend using a push pull controller for this case. Push pull controller allows to deliver more power with a limited…
您好
根据官方datasheet显示有两种模式您可以按照您的需求进行选择：
1、这种模式是您说的GND接电容接地的模式，是达到限电流保护模式，优势就是可以在突发情况下保护您的电路，缺点是保护后没有自动恢复。
Latch-off mode is active when the DELAY pin connects to GND through a capacitor. When a current limit is reached, the output current holds at the setting…

Part Number: BQ25185
Hello, is my schematic correct and does it meet the following requirements: connecting to a flexible solar panel and integrating a stable 4.5V output as the main power distribution bus? The internal Power Path management circuit should…
Hello,
Yes, the BQ25185 meets these requirements. Battery tracking VINDPM makes it great for use with solar panels, the battery overcurrent protection (BATOCP) is 3.125A, the highest available input current limit (ILIM) setting is 1.1A, and supplement…
您好
The MotorCurrent variable just for indication purpose, this uses limited resolution.
The internal implementation runs truncation to eliminate the noise and this impacts accuracy.
Also, phase current should be tuned to well align with BEMF as mentioned…

Hi,
I think it is power limited (maby peak current limit or short circuit protection)
Please share more waveforms: transformer primary current, SW, Vin, Vout, gate signal.
Plesase also share the schematic.
