Hi,
How can I request the latest SIMPLIS models of the following two parts?
TPS922055 and TPS92641
Currently the TPS922055DMTREVM is out of stock, so we urgent…
Part Number: TPS922055 Tool/software: Hello,
I'm using TPS922055 in the design to drive the LEDs, Setting the maximum LED current to 2.4A by using a 0.082 ohm sense resistor.
But when I powered the board and measured the output current, I got…
Part Number: TPS922055 Tool/software: Hi team,
1. Does the TPS922055 work with 200kHz switching frequency, and dimming PWM is 20kHz. Is it able to have the output current PWM rising time and falling time shorter than 2us? I saw the user guide of EVM…
Part Number: TPS922055 I'm looking for a simple circuit using TPS922055 chips to control LED lighting in a vision system.
The goal is to control the TPS922055 via an ESP32 to create pulses during camera exposure.
I also need to be able to change the…
