    Calculating surface temperature of stepup converter

    Hola I am using a TPS62122 stepup converter. This have junction to ambient thermal resistance set to 114.4°C/W and a max load of 75mA. Am I correct that on a PCB which have no extra cu for thermal disipation that when this converter is generating a 3.5V form a 12V supply, the temperature may...
