11. Application Notes
It is strongly recommended to connect the blocking capacitors at V
CC
and V
S
as close as possible to the power supply and GND
pins.
Recommended value for capacitors at V
S
:
Electrolytic capacitor C > 22µF in parallel with a ceramic capacitor C = 100nF. The value for electrolytic capacitor depends on
external loads, conducted interferences and reverse conducting current I
Out1,2,3
(see “Absolute Maximum Ratings” on page 7).
Recommended value for capacitors at V
CC
:
Electrolytic capacitor C > 10µF in parallel with a ceramic capacitor C = 100nF.
To reduce thermal resistance it is recommended to place cooling areas on the PCB as close as possible to the GND pins.
