The recommended input capacitor value is 10uF to 22uF, depending on the input voltage and output current requirements. A larger capacitor value can help to reduce input voltage ripple and improve output voltage regulation.
To ensure the LM2735XMFX/NOPB operates within its SOA, ensure that the input voltage, output current, and ambient temperature are within the recommended operating conditions specified in the datasheet. Additionally, ensure that the device is properly heatsinked and that the thermal design is adequate to prevent overheating.
The maximum output current capability of the LM2735XMFX/NOPB is 3A. However, the actual output current capability may be limited by the input voltage, output voltage, and thermal design of the system.
To minimize EMI and ensure reliable operation, follow good PCB layout practices such as separating the input and output stages, using a solid ground plane, and minimizing loop areas. Additionally, ensure that the PCB is designed to minimize thermal resistance and provide adequate heat dissipation.
The recommended output capacitor value is 10uF to 47uF, depending on the output voltage and output current requirements. A larger capacitor value can help to improve output voltage regulation and reduce output voltage ripple.
