Part Number: TPS923655DMTREVM Other Parts Discussed in Thread: TPS922055DMTREVM , Tool/software: Dear Team,
My customer is going to evaluate the TPS923655DMTREVM and the TPS922055DMTREVM. They would like to refer the PCB layouts of those. Then, they want…
Hi Amritha,
If you want to switch on/off the LED almost instantaneously in a very high speed ( varying frequency from KHz - MHz range ), you should consider using the shunt FET PWM dimming feature of TPS92641.

Hi Steven,
They use "PWM dimming mode" with ADIM/HD input pin = always H level by shorting between 1 and 2 of J7 on TPS923655DMTREVM and input 15us one shot pulse to EN/PWM pin.
Thank you and best regards, Kazuya Nakai.
Hi Gaston,
