( ) the derating curve in figure 55(b) indicates the power that t he ic can consume with reference to ambient temperature. power consumption of the ic begins to attenuate at certai n temperatures. this gradient is determined by thermal resistance ( ja), which depends on the chip size, power consumpti on, package, ambient temperature, package condition, wind velocity, etc. this may also vary even when the sa me of package is used. thermal reduction curve indicates a reference value measured at a specifi ed condition. figure 56(c) and 56(d) shows an example of the derating curve for ba3472y, ba3472w, ba3474y and ba3474w. when using the unit above ta=25 , subtract the value above per degree . mounted on a fr4 glass epoxy 4 layers pcb 70mm 70mm 1.6mm (occupied copper area 70mm 70mm). when the part is mounted on fr 4 glass epoxy 4 layers pcb 70mm 70mm 1.6mm (occupied copper area 70mm 70mm). ssop-b8 package : pd at 125 is 165mw so vcc has to be below 27v. msop8 package : pd at 125 is 150mw so vcc has to be below 25v. ssop-b14 package : pd at 125 is 270mw so vcc has to be below 22v.
