TPS65287RHAR Frequently Asked Questions (FAQ)

  • Texas Instruments provides a recommended layout and placement guide in the TPS65287RHAR datasheet (Section 10.2) and in the application note 'TPS65287RHAR Layout and Placement Guidelines' (SLUAUH5). It's essential to follow these guidelines to ensure proper thermal performance, noise reduction, and overall system reliability.

  • The TPS65287RHAR has a programmable output voltage range of 0.9 V to 3.3 V. To select the correct output voltage, consider the voltage requirements of your load, the input voltage range, and the desired output voltage accuracy. You can use the TPS65287RHAR's voltage-setting resistors (R1 and R2) to set the output voltage according to the formula provided in the datasheet (Section 7.3.1).

  • The TPS65287RHAR has an absolute maximum input voltage rating of 6.5 V. However, the recommended input voltage range is 3.5 V to 5.5 V. Operating the device outside of this range may affect its performance, efficiency, and reliability.

  • To ensure proper thermal performance, follow the recommended layout and placement guidelines, and provide adequate heat sinking and airflow around the device. The TPS65287RHAR has a thermal shutdown feature that turns off the device when the junction temperature exceeds 150°C. Monitor the device's temperature using the thermal monitoring pin (TMP) and take corrective action to prevent overheating.

  • The EN (enable) pin is an active-high input that enables or disables the TPS65287RHAR. When EN is high, the device is enabled, and when EN is low, the device is disabled. Use the EN pin to control the power-on sequence, implement power-saving modes, or reset the device. Ensure that the EN pin is properly biased and decoupled to prevent unwanted device behavior.
