A thermal pad on the bottom of the module should be connected to a large copper area on the PCB to dissipate heat. Keep the thermal path short and use multiple vias to reduce thermal resistance.
Choose an input capacitor with a voltage rating higher than the maximum input voltage, and an ESR (Equivalent Series Resistance) that meets the module's requirements. A low-ESR ceramic capacitor is recommended.
Use a pi-filter (L-C-L) or a simple capacitor at the input to filter out high-frequency noise and ensure stable operation. The filter values depend on the specific application and input voltage.
Implement overcurrent protection (OCP) and overtemperature protection (OTP) in your design. The module has built-in OCP, but OTP requires external circuitry. Monitor the module's temperature and current output to prevent damage.
Use a low-ESR ceramic capacitor with a value between 10uF to 22uF to ensure stability and low output ripple. The output capacitor should be placed close to the module's output pins.
