Hi,
We got a question from customer about TPS61185.
Could you help us?
[Question]
Our customer measured Vin transient response. They expected the IC regulate LED current during Vin transient. But the result is not. Please see attached file. They have questions.
TPS61185 Vin transient response_17Mar28.pdf
- Why does the IC disable current sink and stop switching during period of Vin falling?
- What is the condition of re-start switching?
Best Regards,
