The maximum power dissipation at TA = 25C can be calculated as below : PD(MAX) = (125C 25C) / (27C/W) = 3.7W for a WL-CSP-48B 3.04x2.99 (BSC) package The maximum power dissipation depends on the operating ambient temperature for the fixed TJ(MAX) and the thermal resistance, JA. The derating curve in Figure 23 allows the designer to see the effect of rising ambient temperature on the maximum power dissipation. Figure 23. Derating Curve of Maximum Power Dissipation Layout Consideration For best performance of the RT5509, the below PCB Layout guidelines must be strictly followed. Place the decoupling capacitors as close as possible to the DVDD pins. For achieving a good quality. The traces of VSPOUTP and VSPOUTN should be kept equal width and length respectively. The Bead + C should be placed close to chip for better EMI performance. The power trace of boost inductor is suggested to place on the external layers for higher current capability. Please place the inductor as close as possible to the chip. 0.0 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 0 25 50 75 100 125 Ambient Temperature (°C) Four-Layer PCB |
