A good PCB layout for the TPS65167ARHAR involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
Choose input capacitors with a voltage rating of at least 1.5 times the maximum input voltage, and output capacitors with a voltage rating of at least 1.5 times the output voltage. The capacitance value depends on the output current and ripple requirements. A general rule of thumb is to use 10uF to 22uF ceramic capacitors for both input and output.
The TPS65167ARHAR is rated for operation from -40°C to 125°C. However, the maximum ambient temperature range depends on the specific application and the thermal design of the system. It's recommended to derate the device's power dissipation according to the ambient temperature.
The TPS65167ARHAR has a built-in overcurrent protection feature that can be enabled by connecting a resistor between the OCP pin and the GND pin. The value of the resistor determines the overcurrent threshold. A lower resistor value sets a higher overcurrent threshold.
Yes, the TPS65167ARHAR is qualified for automotive and high-reliability applications. It meets the AEC-Q100 standard for automotive applications and is manufactured using a high-reliability process. However, it's essential to follow the recommended design and layout guidelines to ensure the device operates within its specifications.
