TPS22945DCKRG4 Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the TPS22945 datasheet (SLVSBE5) and in the application note 'TPS22945 PCB Layout Guidelines' (SLVAUH5). It's essential to follow these guidelines to minimize noise, ensure proper thermal dissipation, and optimize performance.
  • The input capacitor value depends on the input voltage, output voltage, and desired output ripple. A general guideline is to use a capacitor with a value between 1uF to 10uF, with a voltage rating at least 1.5 times the input voltage. TI's Webench Power Designer tool can help with capacitor selection.
  • The maximum output current of the TPS22945 is 5A, but it's limited by the thermal dissipation of the package and the PCB design. Ensure proper thermal design and heat sinking to achieve the maximum output current.
  • The TPS22945 is rated for operation up to 125°C (TJ). However, the device's performance and reliability may degrade at high temperatures. Ensure proper thermal design, heat sinking, and derating to maintain reliability in high-temperature environments.
  • The TPS22945 has a built-in overcurrent protection feature. Connect a sense resistor (Rs) between the output and GND, and set the overcurrent threshold (OCT) pin to the desired value. The device will limit the output current to the set threshold during an overcurrent event.
