TPS61165: CTRL PWM control

K.Shidara

Part Number: TPS61165

Hi Team,

Would you advise about PWM control of TPS61165 below?

In case of not using EASY scale mode,

1. Is it possible to drive the LED output current with PWM (Imax-Imin)?
2. Please let me know what the operation is for each PWM frequency of CTRL.

Thanks

Best regards,

Shidara

    Hi Sir,

        TPS61165 can do support two kinds of dimming mode: PWM mode/Easy-Scale Mode.

        1. For PWM mode, it supports 5k to 100kHz dimming frequency and changes the internal reference with the duty cycle; the different frequency has the similar performance.

        2. For Easy Scale mode, you can refer to  Table 3 in the datasheet for the detailed reference change with different D4 to D0;
