STK433-240A-E no. a1490-8/10 [example] when the ic supply voltage, v cc , is 24v and r l is 6 , the total power dissipation, pd, within the hybrid ic, will be a maximum of 60w at 1khz for a continuo us sine wave signal according to the pd-p o characteristics. for the music signals normally handled by audio amplifiers, a value of 1/8p o max is generally used for pd as an estimate of the power dissipation based on the type of continuous signal. (note that the factor used may differ depending on the safety standard used.) this is: pd 47.0w (when 1/8p o max. = 5.0w, p o max. = 40w). the number of power transistors in audio amplifier block of these hybrid ics, n, is 6, and the thermal resistance per transistor, j-c, is 4.2 c/w. therefore, the required heat sink thermal resistance for a guranteed ambient temperature, ta, of 50 c will be as follows. from formula (1)' c-a < (125 ? 50)/47.0 < 1.59 from formula (2)' c-a < (150 ? 50)/47.0 ? 4.2/6 < 1.42 therefore, the value of 1.42 c/w, which satisfies both of these formulae, is the required thermal resistance of the heat sink. note that this thermal design exampl e assumes the use of a constant-voltage power supply, and is therefore not a verified design for any particular user?s end product. stk433-200(a)-e series sta nd-by control, mute control, load-short protection & dc offset protection application 2 3 4 5 6 7 8 9 10 11 12 13 14 1 15 ch1 out gnd +v cc -v cc stk433-200(a)-e series st-by 56k gnd ch2 in gnd ch1 in +v cc ch1 in ch1 nf ch2 in ch2 nf ch2 out ch1 out -v cc sub gnd +pre st-by ch1 out ch2 out -pre 0.22 /2w 6.8k (*1) (ex) 2.7k 0.22 /2w 56k 56k load short protection circuit 22k 56k 1k 0.1 f 10k 100k 1k 33k 2k 33 f / 10v 10k 10k 10k 2.2k gnd play mute st-by mute +5v +5v stand-by control mute control mute control h: single mute l: normal stand-by control(ex) h: operation mode(+5v) l: stand-by mode(0v) dc offset protection (*1) the voltage applied to the stand-by pin (#13) must not exceed the maximum rated value (vst max). latch up circuit 16 17 18 19 ch3 in ch3 nf ch3 out ch3 out 56k 6.8k ch3 in 10k gnd ch2 out ch3 out 82k 82k 82k 22 f 22 f 100k (*4) r2 0.22 /2w 56k 56k 6.8k
