Hi,
My customer use the TPS61165.
They have a question about open LED Protection.
They use PWM control. When Open LED circuit, output voltage doesn't exeed 38V. And IC is shutdown. Then output voltage drop to input voltage. But, after 3.8ms output voltage raise around 38V. Then IC is shutdown. This situation occurs repeatedly. Is it right?
When use 1-wire control. When Open LED circuit, output voltage doesn't exeed 38V. And IC is continuously shutdown. So, output voltage is fixed to input voltage.
They want to same result when using PWM control.
