TPS65273VRHHR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the TPS65273VRHHR datasheet, but it's also recommended to follow the guidelines in the TI application note 'TPS65273 PCB Layout Guidelines' (SLUAAC7) for optimal performance and thermal management.
  • The output capacitor selection depends on the output voltage, output current, and desired ripple voltage. TI 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. Refer to the TI application note 'Output Capacitor Selection for Switching Regulators' (SLUAAC6) for more information.
  • The TPS65273VRHHR has an absolute maximum input voltage rating of 18V, but the recommended maximum input voltage is 15V to ensure reliable operation and prevent damage to the device.
  • The TPS65273VRHHR has a built-in overcurrent protection feature that can be enabled by connecting a resistor between the OCP pin and GND. The value of the resistor determines the overcurrent threshold. Refer to the datasheet for more information on how to calculate the resistor value.
  • The thermal shutdown temperature of the TPS65273VRHHR is typically around 150°C, but it can vary depending on the specific device and operating conditions. Refer to the datasheet for more information on thermal shutdown and thermal management.
