  • RE: [FAQ] What is the maximum switching duty cycle of TPS922055 / TPS922054 / TPS922053 / TPS922052?

    Resolved
    For TPS922055 / TPS922054 / TPS922053 / TPS922052 to regulate the output current to the target value, you should make sure that LED (string) voltage < input voltage. For TPS922055 / TPS922054 / TPS922053 / TPS922052 to regulate the output current to…

  • TPS922053: Will this LED driver work with a target current of 0.2-1A?

    Part Number: TPS922053 Other Parts Discussed in Thread: TPS922052 , Tool/software: Hi! I've read the datasheet for the TPS92205x, and I couldn't understand if the LED has a minimum working current under-which it will not work. I saw the I(LIM) under…

  • TPS922053: Use as a purely Constant Voltage device using the UVP resistor divider

    Part Number: TPS922053 Tool/software: The datasheet is a bit vague about the usage of the Constant Voltage mode. I have a camera that needs 12V and pulls around 300mA. For BOM optimalisation I would like to re-use the TPS922053. Input voltage is 24V. …
