APPLIED CIRCUIT BOARD EXAMPLES
PRECAUTIONS
1. Please locate C5 close to terminal No.10.
2. Please locate L6 close to terminal No.3.
3. Please locate C9 close to L6.
4. Please connect exposed GND PAD (bottom side of IC) to PCB GND using through holes as many as
5. Please design the PCB structure that the dielectric thickness between the surface layer and the GND
possible.
layer (directly under) is set to 0.2mm or more, about PCB of this device and external parts. However,
the terminal of TAB GND of this device and the GND of external parts does not have these
restrictions. Please design the GND layer pattern that can reduce a parasitism GND inductance as
much as possible.
