TPS92661EVM-001 each string has a max current rating of approximately 135 mA.
Is this limitation from only BuckController(LM3409) current limit ?
Our customer would like to evaluate this board around 500mA with their using LED.
Please advise us modification point of TPS92661EVM-001 for their evaluation requirement.
