The first path is the junction to the case (JC) which is defined by the package style, and the second path is case to ambient (CA) thermal resistance which is dependent on board layout. The final operating junction temperature for any set of conditions can be estimated by the following thermal equation: TJUNC = TAMB + PD (JC) + PD (CA) = TAMB + PD (JA) The CMPWR163-33MA with the Power MSOP packaging option uses a thermally enhanced MSOP-8 package where all the GND pins (5 through 8) are integral to the leadframe. When this package is mounted on a double sided printed circuit board with two square inches of copper allocated for "heat spreading", the resulting JA is 70C/W. Based on a maximum power dissipation of 0.255W (Load x Vin-Vout = 150mA x 1.7V) with an ambient of 70C the resulting junction temperature will be: TJUNC = TAMB + PD (JA) = 70C + 0.255W (70C/W) = 70C + 18C = 88C 7KHUPDO FKDUDFWHULVWLFV ZHUH PHDVXUHG XVLQJ D GRXEOH VLGHG ERDUG ZLWK WZR VTXDUH LQFKHV RI FRSSHU DUHD FRQQHFWHG WR WKH *1' SLQV IRU KHDW VSUHDGLQJ Measurements showing performance up to a junction temperature of 125C are presented in )LJXUH . They were performed under light load conditions (5mA); this allows the ambient temperature to be representative of the internal junction temperature. Note: The use of multi-layer board construction with separate ground and power planes will further enhance the overall thermal performance. In the event of no copper area being dedicated for heat spreading, a multi-layer board construction using only the minimum size pad layout will typically provide the CMPWR16333MA (in an MSOP package) with an overall JA of 90C/W, which allows up to 600mW to be dissipated safely. 100 GROUND CURRENT [uA] OUTPUT CHANGE [mV] 3OHDVH FRQVXOW &$0' 7HFKQLFDO 6XSSRUW IRU DVVLVWDQFH ZLWK WKHUPDO DQDO\VLV RI WKH &03:5 LQ HLWKHU DQ 0623 RU 627 SDFNDJH ZLWK UHVSHFW WR D VSHFLILF DSSOLFDWLRQ 2XWSXW 9ROWDJH &KDQJH YV 7HPSHUDWXUH P$ ORDG 50 40 30 20 10 0 -10 -20 -30 -40 -50 -50 -25 0 25 50 75 100 125 TEMPERATURE [oC] *URXQG &XUUHQW YV 7HPSHUDWXUH 80 60 40 20 0 0 25 50 75 100 125 TEMPERATURE [oC] )LJXUH &03:5 3HUIRUPDQFH YV 7HPSHUDWXUH 2002 California Micro Devices Corp.
