A good PCB layout for the TPS65286RHDR involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. It's also recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
The output voltage of the TPS65286RHDR can be set using the VID pins. The recommended output voltage range is 0.7V to 3.3V. Choose an output voltage that meets the requirements of your load, taking into account factors such as voltage tolerance, current requirements, and power dissipation.
The TPS65286RHDR can handle input voltages up to 6.5V. However, it's recommended to operate the device within the specified input voltage range of 2.7V to 5.5V for optimal performance and reliability.
To ensure the stability of the output voltage, it's recommended to use a minimum output capacitance of 10uF, with a voltage rating of at least 1.5 times the output voltage. Additionally, the output voltage can be stabilized by adding a small ceramic capacitor (e.g., 100nF) in parallel with the output capacitor.
The TPS65286RHDR has a thermal derating of 2.5mW/°C above 25°C. This means that the device's power dissipation capability decreases as the temperature increases. To ensure reliable operation, it's essential to consider the thermal derating when designing the application, especially in high-temperature environments.
