11. Application Notes
It is strongly recommended to connect the blocking capacitors at V
CC
and V
S
as close as possi-
ble to the power supply and GND pins.
Recommended value for capacitors at V
S
:
Electrolytic capacitor C > 22 µF in parallel with a ceramic capacitor C = 100 nF. The value for
electrolytic capacitor depends on external loads, conducted interferences and reverse conduct-
ing current I
Out1,2,3
Section 4. ”Absolute Maximum Ratings” on page 7
).
Recommended value for capacitors at V
CC
:
Electrolytic capacitor C > 10 µF in parallel with a ceramic capacitor C = 100 nF.
To reduce thermal resistance it is recommended to place cooling areas on the PCB as close as
possible to the GND pins and to the die pad.
