TPS62750DSKR datasheet by Texas Instruments

TPS62750DSKR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  TI provides a recommended PCB layout in the datasheet (Figure 23) and in the TPS62750DSKR Evaluation Module documentation. It's essential to follow these guidelines to minimize noise, ensure proper thermal performance, and achieve optimal output voltage regulation.
• How do I select the correct output capacitor for my application?
  The output capacitor selection depends on the output voltage, output current, and desired output ripple. TI recommends using a low-ESR ceramic capacitor (X5R or X7R dielectric) with a minimum capacitance of 10uF and a voltage rating of at least 1.5 times the output voltage. Refer to the datasheet (Section 7.2.2) for more information.
• What is the maximum input voltage that the TPS62750DSKR can handle?
  The TPS62750DSKR has an absolute maximum input voltage rating of 6.5V. However, the recommended operating input voltage range is 2.3V to 5.5V. Exceeding the absolute maximum rating can damage the device.
• How do I ensure the device operates within the recommended junction temperature range?
  To ensure the device operates within the recommended junction temperature range (TJ = -40°C to 125°C), follow proper thermal design practices, such as using a thermal pad, thermal vias, and a heat sink (if necessary). Also, ensure good airflow and avoid blocking the thermal pad.
• What is the purpose of the EN pin, and how do I use it?
  The EN (Enable) pin is used to enable or disable the device. When EN is high (logic level), the device is enabled, and when EN is low (logic level), the device is disabled. This pin can be used to implement power sequencing, shutdown, or low-power modes in your application.
