TPS23785BPWPR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the TPS23785 evaluation module documentation, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
  • The input capacitor selection depends on the input voltage ripple, output current, and operating frequency. A general guideline is to choose a capacitor with a voltage rating at least 1.5 times the maximum input voltage, and a capacitance value that ensures the input voltage ripple is within the recommended range (typically 1-5% of the input voltage).
  • The maximum output current of the TPS23785BPWPR is 3.5A, but this can be limited by the thermal performance of the device and the PCB. It's essential to ensure proper thermal management and follow the recommended layout guidelines to achieve the maximum output current.
  • The TPS23785BPWPR has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor and capacitor network. The OCP threshold can be set by selecting the appropriate resistor value, and the device will limit the output current to prevent damage in case of an overcurrent event.
  • The TPS23785BPWPR is rated for operation up to 105°C, but the device's performance and reliability may be affected at high temperatures. It's essential to ensure proper thermal management and follow the recommended layout guidelines to minimize thermal resistance and ensure reliable operation.
