A good thermal design should include a solid ground plane, thermal vias under the device, and a heat sink if necessary. Refer to the TI application note 'TPSM82480MOPT Thermal Design Considerations' for more information.
To ensure a stable and accurate output voltage, make sure to use a high-quality output capacitor with a low ESR, and follow the recommended output capacitor selection guidelines in the datasheet. Additionally, ensure the input voltage is within the recommended range and the device is operated within its specified temperature range.
The maximum input voltage that can be applied to the TPSM82480MOPT is 18V. Exceeding this voltage may damage the device. It's recommended to add input voltage protection, such as a TVS diode, to prevent overvoltage conditions.
The output current capability of the TPSM82480MOPT depends on the input voltage, output voltage, and ambient temperature. Refer to the datasheet's 'Output Current Capability' section for the calculation formula and graphs to determine the maximum output current for your specific application.
The recommended input capacitor value is 10uF to 22uF, with an X5R or X7R dielectric type. This ensures low ESR and high ripple current capability to handle the device's high-frequency switching.
