the tps61088 evm board can't output more than 2A current, I just changed the feedback resistor to achieve 5V boot to 11V, when load is heavy, output voltage is not correct, and also pull down the input voltage to 3V, and the board make noise, my input power is DC regulated voltage and can output more than 10A, so what is reason resulting in this problem？
