TPS75100 / Duration of tPWM(min)

Hi All,

Please let me know the duration of tPWM(min) which is specified as 33us at recommended operating conditions. Is it a duration between 0.4V of ENx and beginning of rising Iout? I understand that the rise time of Iout depend on the kind of LED.

Best Regards,

    Hello,

    You are correct, the tPWM(min) represents the minimum recommended pulse width.  This parameter is limited by the delay from enable rising to the Iout response time.   33 us represents the maximum possible delay between EN rising to IOUT rising

    Regards,
