TPS65263RHBR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended layout and placement guide in the TPS65263RHBR datasheet (Section 10.2) and in the application note 'TPS65263RHBR Layout and Placement Guidelines' (SLUAU93). It's essential to follow these guidelines to ensure proper thermal performance, noise reduction, and overall system reliability.
  • The output capacitor selection depends on the output voltage, output current, and desired ripple voltage. Texas Instruments recommends using a low-ESR ceramic capacitor with a minimum capacitance of 10uF and a voltage rating of at least 1.5 times the output voltage. The application note 'TPS65263RHBR Output Capacitor Selection' (SLUAU94) provides more detailed guidance.
  • The TPS65263RHBR has an absolute maximum input voltage rating of 18V. However, the recommended maximum input voltage is 15V to ensure reliable operation and to prevent damage to the device. It's essential to ensure that the input voltage does not exceed 15V to maintain the device's reliability and performance.
  • The TPS65263RHBR output voltage can be configured using the FB pin and an external resistor divider network. The datasheet (Section 7.3.5) provides a formula to calculate the required resistor values for a specific output voltage. Additionally, Texas Instruments offers a voltage calculator tool to simplify the process.
  • The thermal derating curve for the TPS65263RHBR is provided in the datasheet (Figure 10-1). The curve shows the maximum output current vs. ambient temperature, allowing designers to determine the maximum output current at a given temperature. This information is essential for ensuring reliable operation and preventing overheating.
