TPS53126RGER Frequently Asked Questions (FAQs)

  • TI provides a recommended PCB layout in the datasheet (Figure 23) and in the TPS53126RGER Evaluation Module User's Guide (SLUU444). Follow these guidelines to minimize noise, ensure proper thermal management, and optimize performance.
  • The input capacitor values depend on the input voltage, output voltage, and desired ripple current. TI recommends using the WEBENCH Power Designer tool or the TPS53126RGER Calculator Tool to determine the optimal input capacitor values for your specific application.
  • The maximum output current capability of the TPS53126RGER is 2.6A. However, the actual output current capability may be limited by the thermal performance of the device, PCB layout, and other system-level factors. Ensure proper thermal management and follow the recommended layout guidelines to achieve the maximum output current.
  • The TPS53126RGER has a built-in OCP and SCP feature. To implement OCP, connect a resistor (RILIM) between the ILIM pin and GND to set the current limit threshold. For SCP, connect a resistor (RSCP) between the SCP pin and GND to set the short-circuit detection threshold. Refer to the datasheet (Section 7.3.5) for more information.
  • The recommended operating temperature range for the TPS53126RGER is -40°C to 125°C. However, the device can operate up to 150°C with derating. Ensure proper thermal management and follow the recommended layout guidelines to maintain optimal performance within the recommended temperature range.
