TPS22934YZVR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the TPS22934YZVR datasheet (section 10.2) and in the TPS22934YZVR Evaluation Module User's Guide. It's essential to follow these guidelines to minimize parasitic inductance and ensure proper operation.
  • The input capacitor value depends on the input voltage, output current, and desired ripple voltage. A general guideline is to choose 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 is 3.4A, but it's limited by the thermal performance of the package and the PCB. Ensure proper thermal design and heat sinking to achieve the maximum output current.
  • The TPS22934YZVR has a built-in OCP feature that can be enabled by connecting the OCP pin to a resistor divider network. The OCP threshold is adjustable by selecting the correct resistor values. Refer to the datasheet (section 7.3.5) for more information.
  • The EN (enable) pin is used to turn the device on or off. Connect the EN pin to a logic signal (e.g., from a microcontroller) to enable or disable the output. When EN is low, the device is in shutdown mode, and the output is disabled.
