LM3644: Flash TIme-Out Duration

Jeffrey Chung1

Part Number: LM3644

Hi TI Team,

I'd like to ask you about the flash time-out duration of this device. I want to design that LED1 and LED2 are turned on during 6msec through PWM signal(Ton=6msec) on STROBE under condition of the flash time-out duration(0000=10ms). Is it the correct configuration or not? I think that this design configuration is no problem. Please check it and let me know.

hi Jeffrey

To turn on 6ms by strobe PWM signal, I think it is fine to set flash time-out 10ms.

Hi Mason,

Thank you for your response. Is there the application note for PWM signal input on STROBE in more detail? Please check it and let me know.

hello Jeffrey

sorry I did not find application note specifically for Strobe. You can refer to the datasheet and if you have any questions on applying STROBR signal, feel free to raise a question.
