TPS82676SIPT datasheet by Texas Instruments

TPS82676SIPT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Texas Instruments provides a recommended PCB layout in the TPS82676SIPT datasheet (section 10.2) and in the TPS82676SIPT Evaluation Module User's Guide (SLUU444). It's essential to follow these guidelines to minimize noise, ensure proper thermal management, and optimize performance.
• How do I select the correct output capacitor for my application?
  The output capacitor selection depends on the output voltage, output current, and desired ripple voltage. TI recommends using a low-ESR ceramic capacitor (X5R or X7R dielectric) with a minimum capacitance of 10 μF and a voltage rating of at least 1.5 times the output voltage. Refer to the datasheet (section 7.3.1) for more information.
• What is the maximum input voltage that the TPS82676SIPT can handle?
  The TPS82676SIPT has an absolute maximum input voltage rating of 6.5 V. However, the recommended operating input voltage range is 2.7 V to 5.5 V. Exceeding the absolute maximum rating can damage the device.
• How do I implement overcurrent protection (OCP) with the TPS82676SIPT?
  The TPS82676SIPT has a built-in overcurrent protection feature. To implement OCP, connect a sense resistor (RSENSE) between the VIN pin and the GND pin. The device will limit the output current to the programmed value (set by the RSENSE resistor) to prevent damage from excessive current.
• What is the thermal derating for the TPS82676SIPT?
  The TPS82676SIPT has a thermal derating of 12.5 mA/°C above 25°C. This means that for every 1°C increase in temperature above 25°C, the maximum output current rating decreases by 12.5 mA. Refer to the datasheet (section 6.3) for more information.
