The recommended input capacitor value is 1uF to 10uF, 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 TPS60400DBVT 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 thermally managed and that the PCB layout is designed to minimize thermal resistance.
The maximum output current that the TPS60400DBVT can deliver is 50mA. However, the actual output current capability may be limited by the input voltage, output voltage, and ambient temperature.
The TPS60400DBVT is rated for operation up to 125°C. However, the device's performance and reliability may be affected at high temperatures. It is recommended to derate the output current and ensure proper thermal management to ensure reliable operation in high-temperature environments.
To minimize EMI with the TPS60400DBVT, ensure that the PCB layout is designed to minimize loop areas and keep sensitive traces away from the device. Use a solid ground plane, and consider using shielding or filtering components to reduce EMI emissions.
