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 ripple and improve output stability.
To ensure the LM2623MM/NOPB operates within its SOA, ensure that the input voltage, output current, and ambient temperature are within the recommended specifications. Also, ensure that the device is properly heatsinked and that the thermal resistance (RθJA) is within the recommended range.
The maximum output current that the LM2623MM/NOPB can deliver is 3A. However, the actual output current may be limited by the input voltage, output voltage, and thermal considerations.
The LM2623MM/NOPB is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's recommended to derate the output current and ensure proper heatsinking to maintain a safe operating temperature.
To reduce EMI when using the LM2623MM/NOPB, ensure that the input and output capacitors are properly decoupled, use a shielded inductor, and keep the layout compact and symmetrical. Additionally, consider adding EMI filters or shielding to the PCB design.
