7 / 11 page BD35390FJ Technical Note 7/10 www.rohm.com 2009.10 - Rev.A © 2009 ROHM Co., Ltd. All rights reserved. ● Heat loss Thermal design must be conducted with the operation under the conditions listed below (which are the guaranteed temperature range requiring consideration on appropriate margins etc); 1: Ambient temperature Ta: 100℃ or lower 2:Chip junction temperature Tj: 150℃ or lower The chip junction temperature Tj can be considered as follows: Most of heat loss in BD35390FJ occurs at the output N-channel FET. The power lost is determined by multiplying the voltage between VIN and Vo by the output current. As this IC employs the power PKG, the thermal derating characteristics significantly depends on the pc board conditions. When designing, care must be taken to the size of a pc board to be used. Power consumption (W) = Input voltage (VTT_IN)-Output voltage (VTT≒1/2VDDQ) ×Io(Ave) Example) Where VTT_IN =1.8V, VDDQ=1.8V, Io(Ave)= 0.5A = 0.45(W) ● Heat dissipation characteristics Power consumption(W) = 1.8(V)-0.9(V) ×0.5(A) (1) mounted on 70mm×70mm×1.6mm glass-epoxy board θ j-c=185.2℃/W (2) With no heat sink θ j-a=222.2℃/W 600 0 25 75 100 125 150 50 200 100 0 [℃] 400 500 300 [mW] (2) 563mW 100℃ (1) 675mW 700 Ambient temperature [Ta] |
