Technical Note

●Notes for use

1. We have paid enough attention to quality control of this product, but it may be destroyed when the absolute

maximum rating of impressed voltage and operating temperature range is exceeded. Because we can’t specify

that is short-mode or open-mode etc while it is destroyed, so please discuss to give physical safety action with

postulating the special mode exceeded absolute maximum rating.

2. About application circuit

Application circuit is recommended, but please fully confirm temperature characteristic etc when using it. Moreover,

please acknowledge that our company can’t confirm enough about patent.

3. About the range of operation power-supply voltage

Circuit function operation at the range of operation ambient temperature is guaranteed when it is in the range of

operation power-supply voltage. About characteristic value, the specification value of electric characteristic can’t

be guaranteed, but the characteristic value doesn’t change rapidly in these ranges.

4. About ground connection

The ground connection shown in application circuit example should equip enough fat GND（FIN） to every ground

connection with shortest pattern drawing, and the pattern shouldn’t interfere the electric characteristic.

5. About input power-supply

The input power-supply shown in application circuit example should equip input pin VCC(1pin) with short enough

pattern drawing, and the pattern shouldn’t interfere the electric characteristic.

6. Please think about permissible power dissipation (Pd) in an actual using status, and do the heat design with

enough margins.

7. Please pay enough attention to the direction and displacement of IC when you install it on PCB. If you install it by

mistake, IC might be destroyed, Moreover, when short-circuit happen by foreign substance entered between

outputs, or output and power supply GND, it will be destroyed.

8. Please note that there is a possibility of malfunction if you use it in strong electromagnetic field.

9. Please set STBY terminal voltage to 0.3V or less when putting it on standby status, to 2.0V or more when putting it

on operation status.

Please do not fix STBY terminal voltage from 0.3V to 2.0V. It may cause malfunction or breakdown.
