A 4-layer PCB with a solid ground plane and thermal vias is recommended. The RT9524GQW's thermal pad should be connected to a large copper area on the PCB to dissipate heat efficiently.
Use a high-quality output capacitor with low ESR and a minimum capacitance of 10uF. Also, ensure the input voltage is stable and within the recommended range, and the output voltage is set correctly using the FB pin.
The RT9524GQW can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V for optimal performance and reliability.
Use an external current sense resistor and a fuse or a PTC thermistor to protect the device from overcurrent. Also, ensure good airflow and a heat sink if necessary to prevent overheating.
The RT9524GQW is rated for operation up to 85°C, but its performance and reliability may degrade at higher temperatures. Consider using a heat sink or a thermal interface material to improve heat dissipation.
