Layout Guidelines

The input capacitor needs not only to be close to the VIN pin, but also to the GND pin in order to reduce input supply ripple. For OUTx, path outputs must be short and wide and avoid parallel wiring and narrow trace. For better thermal performance, TI suggest to make copper polygon connected with each pin bigger.
