Application Notes

It is strongly recommended to connect the blocking capacitors at V

ble to the power supply and GND pins.

Recommended value for capacitors at V

electrolythic capacitor C > 22 µF in parallel with a ceramic capacitor C = 100 nF. Value for elec-

trolytic capacitor depends on external loads, conducted interferences and reverse conducting

current I

Recommended value for capacitors at V

electrolythic 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 GND pins.
