Maxim provides a recommended PCB layout in the application note AN1991, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
The 73S8024RN-IMR/F has a thermal pad on the bottom of the package, which should be connected to a thermal plane on the PCB to dissipate heat. A thermal interface material (TIM) can be used to improve heat transfer. Additionally, ensure good airflow around the device and avoid blocking the airflow with nearby components.
The recommended input capacitor value is 10uF to 22uF, with a low ESR (Equivalent Series Resistance) and a voltage rating of at least 6.3V. A ceramic or tantalum capacitor is recommended, as they have low ESR and are suitable for high-frequency switching applications.
The 73S8024RN-IMR/F has an enable pin (EN) that should be driven high to enable the device. During power-up, ensure that the input voltage (VIN) is stable and within the recommended range before driving the EN pin high. During power-down, drive the EN pin low before removing the input voltage.
The 73S8024RN-IMR/F has a maximum output current capability of 2A, but this can be limited by the thermal performance of the device and the PCB. Ensure that the device is properly cooled and the output current is within the recommended range to avoid overheating.
