TPS61098DSER Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS61098DSER involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. Additionally, it's recommended to use a separate power plane for the input voltage and to keep the noise-sensitive analog traces away from the switching node.
  • The inductor value depends on the input voltage, output voltage, and desired switching frequency. A good starting point is to use the inductor value recommended in the datasheet. You can also use the following formula: L = (Vin - Vout) / (ΔI * f_sw), where ΔI is the desired inductor ripple current and f_sw is the switching frequency.
  • The TPS61098DSER is rated for operation from -40°C to 125°C. However, the device's performance and reliability may degrade at extreme temperatures. It's recommended to operate the device within a temperature range of -20°C to 85°C for optimal performance.
  • Yes, the TPS61098DSER is qualified for automotive and high-reliability applications. It meets the AEC-Q100 standard for automotive applications and is also suitable for industrial and medical applications that require high reliability.
  • Proper thermal management involves providing a good thermal path from the device to a heat sink or the PCB. Use a thermal interface material (TIM) to fill the gap between the device and the heat sink, and ensure good airflow around the device. The maximum junction temperature (Tj) should not exceed 150°C.
