    Hi Derek,

        Please refer to our TPS61197EVM for the schematic.

        And please share your output LED characters.

        It seems you don't have used the electronic capacitor, for such high current and high voltage applications with PWM dimming, it should add an electronic capacitor at the output side to reduce the output ripple.

    BR
