Temperature and Reliability

The reliability of an IC is highly dependent on its operating tempera-

ture. Design  should pay particular attention to ensuring ample space

for radiating heat.

Be sure to apply silicon grease to the IC before attaching a heatsink,

and to secure it firmly to the heatsink.

Other important items to be considered regarding heat radiation in-

clude air convection during operation.

■

Calculating Internal Power Dissipation (P

D

)

P

D

 is given by the following formula:

P

D

=I

O

•[V

IN(mean)

–V

O

]

Determine the size of the heatsink according to the relationship be-

tween allowable power dissipation and ambient temperature.

■

Setting DC Input Voltage

The waveform of a DC input voltage is shown below.

When setting the DC input voltage, pay attention to the following:

●

V

IN(min)

 must be no less than the sum of output voltage and dropout

voltage.

●

V

IN(max)

 must be no more than the maximum rated DC input volt-

age.

■

Heatsink Design

The maximum junction temperature T

j(max)

 given in the absolute maxi-

mum ratings is specific to each product type and must be strictly

observed. Thus, thermal design must consider the conditions of use

which affect the maximum power dissipation P

D(max)

 and the maxi-

mum ambient temperature T

a(max)

.

To simplify thermal design, the relationship between these two pa-

rameters has been presented in a graph, the T

a

-P

D

 characteristic

graph. Thermal design should include these steps:

1. Obtain the maximum ambient temperature T

a(max)

.

2. Obtain the maximum power dissipation P

D(max)

.

3. Look for the intersection point on the T

a

-P

D

 characteristic graph

and determine the size of the heatsink.

The size of the heatsink has now been obtained. However, in actual

applications, a 10 to 20% derating factor is introduced. Moreover, the

heat dissipation capacity of a heatsink highly depends on how it is

mounted. Thus, it is recommended to measure the heatsink and case

temperature in the actual operating environment.

The T

a

-P

D

 characteristics for each product type are provided for ref-

erence purposes.

Recommended Silicone Grease

• Shin-Etsu Chemical Co., Ltd.:  G746

• GE Toshiba Silicone Co., Ltd.:  YG-6260

• Dow Corning Toray Silicone Co., Ltd.:  SC102

Please be careful when selecting silicone grease since the oil in some

grease may penetrate the product, which will result in an extremely

short product life.

■

Others

• Devices can not be operated in parallel to increase current.

• An isolation type diode is provided from input to ground and also

from output to ground. These may be destroyed if the device is re-

verse biased. In this case, use a diode with low VF to protect them.

■

Rectifier Diodes for Power Supplies

To rectify the AC input using rectifier diodes in power supplies, use

any of the SANKEN rectifier diodes shown in the following list. (Use

axial type diodes in a center-tap or bridge configuration.)

 adjustment by raising ground voltage

*5: Output is ON even when output control terminal V

 is open. Each input level is equivalent to LS-TTL. Therefore, it may be directly driven by an

LS-TTL circuit.

*6. When setting output voltage to 5V or less, input voltage needs to be set to 6V or over to operate stably.

1. Variable output voltage with a single external resistor

The output voltage may be increased by inserting resistor R

EX 

between

terminals No.4 (sensing terminal) and No.3 (output terminal). The cur-

rent I

REX

 flowing into terminal No.4 is 1mA (typ.), therefore the adjusted

output voltage V

OUT

 is:

=V

*V

: output voltage of SI-3000F series

However, the internal resistor (between terminals No. 4 and No.1) is a

semiconductor resistor, which has approximately thermal characteris-

tics of +0.2%/

°

C.

It is important to keep the thermal characteristics in mind when adjust-

ing the output voltage.

2. Variable output voltage with two external resistors

The output voltage may be increased by inserting resistors R

EX1

 be-

tween terminals No.4 (sensing terminal) and No.3 (output terminal) and

R

EX2

 between terminals No.4 and No.1 (ground terminal).

The current I

4IN

 flowing into terminal No.4 is 1mA (typ.) so the thermal

characteristics may be improved compared to the method shown in 1

by setting the external current I

REX1

 at approximately 5 times the value

of I

4IN

 (stability coefficient S=5).

The adjusted output voltage V

 in this case is:

Note: In the SI-3000F series, the output voltage increase can be ad-

justed as mentioned above. However, when the rise is set to ap-

proximately 10V compared to output voltage V

04

, the necessary

output current may not be obtained due to the S.O.A. protection

circuit in the SI-3000F series.

Note on Thermal Protection:

The thermal protection circuit is intended for
protection against heat during instantaneous
short-circuiting. Its operation is not guaran-
teed for continuous heating condition such
as short-circuiting over extended periods of
time.

*5: Output is ON even when output control terminal V

C

 is open. Each input level is equivalent to LS-TTL. Therefore, it may be directly driven by an

LS-TTL circuit.

*6: A foldback type overcurrent protection circuit is built into the I

C

 regulator (excluding SI-3033C). Therefore, avoid using it for the following applica-

tions as it may cause starting errors:

(1) Constant current load (2) Plus/minus power (3) Series power (4) V
