TPS92641: about the frequency

Part Number: TPS92641

Tool/software:

Hi teams,

TPS92641 wants to achieve strobe function with a frequency of 10K, but using UDIM pin PWM control can only achieve 3K.

How to achieve higher frequencies? Is it through SDIM pins?

    Hi Chu

    Can you please share where did you see the spec for UDIM f_res<3k? 

    Yes the external shunt FET pwm dimming is recommended for higher frequency and time resolution PWM dimming.

    Can you please kindly share what's the customer and the EE&application needs?

    Thanks and best regards.
