9. Design Notes

PCB circuit trace design and component layout significantly affects operation, EMI noise, and power dissipation.

Therefore, pay extra attention to these designs.

Figure 9-1 shows the circuit design example.

The input capacitor C1 and the output capacitor C2 and C3 are connected to each functional pin (ST pin, OUT1 pin

and OUT2 pin) and GND pin as close as possible.
