STMicroelectronics recommends a 2-layer PCB with a thermal pad connected to a large copper area on the bottom layer to dissipate heat efficiently.
Implement a thermal management strategy, such as heat sinks or fans, to keep the junction temperature below 150°C. Also, ensure proper PCB design and layout to minimize thermal resistance.
A 10uF to 22uF X7R or X5R ceramic capacitor is recommended for input decoupling, placed as close to the VIN pin as possible.
Implement overvoltage protection (OVP) and undervoltage protection (UVP) circuits to prevent damage from voltage transients and faults. STMicroelectronics recommends using a voltage supervisor IC for this purpose.
A 10uF to 22uF X7R or X5R ceramic capacitor is recommended for output filtering, placed as close to the VOUT pin as possible.
