TPS40170RGYT Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS40170RGYT 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 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 specific application, but a general guideline is to use 10-22uF for the input capacitor and 22-47uF for the output capacitor.
  • The TPS40170RGYT is rated for operation from -40°C to 125°C, but the maximum ambient temperature range depends on the specific application and the thermal design of the system. A general guideline is to keep the ambient temperature below 85°C for reliable operation.
  • The TPS40170RGYT has a built-in overcurrent protection feature that can be enabled by connecting a resistor between the OCSET pin and the GND pin. The value of the resistor determines the overcurrent threshold. A general guideline is to choose a resistor value that sets the overcurrent threshold to 1.5-2 times the maximum expected load current.
  • Yes, the TPS40170RGYT is qualified for automotive and high-reliability applications. It meets the requirements of the AEC-Q100 standard for automotive applications, and is also suitable for use in industrial and medical applications that require high reliability.
