TPS92512: TPS92512 PWM dimming frequency

yy lee

Part Number: TPS92512

TPS92512 LED driver, our customer's existing case, may need high-frequency PWM dimming (maximum 20KHz). Please help confirm, this IC maximum support PWM dimming frequency to how many Hz.

YY,

Section 8.3.5 of the datasheet explains the PWM dimming function. It states that "the dimming frequency range is 100Hz to 1kHz."

Thank you for your reply,In fact, there is not a max PWM dimming frequency as such in specification. It’s all depending on end application’s requirements.If the dimming accuracy is not high, I think it can be supported.
