TPS65235-1RUKT Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS65235-1RUKT involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the switching node (SW pin) away from sensitive analog nodes. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
  • The inductor value depends on the input voltage, output voltage, and output current. A good starting point is to use the inductor value recommended in the datasheet (e.g., 2.2 μH). Then, adjust the value based on the specific application requirements and efficiency targets.
  • The TPS65235-1RUKT is rated for operation from -40°C to 125°C. However, the device's performance and reliability may degrade at extreme temperatures. It's essential to ensure proper thermal management and consider derating the device's performance at high temperatures.
  • The TPS65235-1RUKT has a built-in OCP feature that can be enabled by connecting the OCP pin to a resistor divider network. The OCP threshold is set by the resistor values and can be adjusted to suit the specific application requirements.
  • Yes, the TPS65235-1RUKT is qualified for automotive and high-reliability applications. It meets the AEC-Q100 standard and is manufactured using a robust process that ensures high reliability and low defect rates.
