Part Number: TPS922055 LED Driver team,
Our customer is driving the same PWM signal on the ADIM and PWM/EN pins. So the device is operating in Flexible Dimming mode. Can you explain the advantages and disadvantages of driving the PWM at a high frequency…
Hi Lorenz,
Thanks for your patience.
If less than 1us on-time is required for 2A output, I would recommend you using shunt FET dimming feature of TPS92641. It is difficult to achieve this with TPS922055.
I would recommend you create a new thread and it…

Part Number: TPS922055 I was wondering if TI could help me with my design of a 1A LED driver. It will be driving a RGB strip, each channel runs at around 900mA @24V. The -055 version was chosen as I intent to use the same design with a 4A LED string in…
Part Number: TPS922055 Hello,
I could not find anywhere in the datasheet the maximum output duty cycle or the minimum difference between Vin and Vout.
I assume, let's say, if the input voltage is 24 V then the maximum output voltage has to be lower…
