A good PCB layout for optimal thermal performance would be to have a large copper area connected to the thermal pad, and to use thermal vias to dissipate heat to the other side of the board. A minimum of 2oz copper thickness is recommended.
To ensure the stability of the output voltage, it is recommended to use a capacitor with a low ESR (Equivalent Series Resistance) and a high ripple current rating. A 10uF ceramic capacitor with an ESR of less than 100mΩ is recommended.
The maximum input voltage that can be applied to the device is 36V, but it is recommended to operate the device within the recommended input voltage range of 3.5V to 36V for optimal performance and reliability.
To protect the device from overcurrent and overheating, it is recommended to use an external current limiting resistor and a thermal protection circuit. The device also has a built-in overcurrent protection and thermal shutdown feature.
The recommended input capacitor value is 1uF to 10uF, and the recommended type is a ceramic capacitor with an X5R or X7R dielectric. The capacitor should be placed as close to the input pin as possible.
