Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow the guidelines in the TI application note 'TPS65276 PCB Layout Guidelines' (SLVAE04) for optimal performance and thermal management.
The output capacitor selection depends on the output voltage, output current, and desired ripple voltage. TI recommends using a low-ESR capacitor with a minimum capacitance of 10uF for each output. The 'TPS65276 Output Capacitor Selection' application note (SLVAE05) provides more detailed guidance.
The TPS65276VRHHR has an absolute maximum input voltage rating of 18V, but the recommended maximum input voltage is 15V to ensure reliable operation and minimize stress on the device.
The output voltage is set using the FB pin and an external resistor divider network. The 'TPS65276 Output Voltage Configuration' application note (SLVAE06) provides a step-by-step guide on how to calculate the required resistor values for a specific output voltage.
The TPS65276VRHHR has a thermal derating of 1.5°C/W above 25°C. This means that the device's power dissipation capability decreases as the ambient temperature increases. The 'TPS65276 Thermal Derating' application note (SLVAE07) provides more information on how to calculate the maximum power dissipation for a given ambient temperature.
