TPS65281-1RGVR Frequently Asked Questions (FAQs)

  • A good PCB layout for the TPS65281-1RGVR involves placing the input capacitors close to the VIN pin, using a solid ground plane, and keeping the high-current paths short and wide. It's also recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
  • The input capacitor should be a low-ESR ceramic capacitor with a value of at least 10uF, and the output capacitor should be a low-ESR ceramic capacitor with a value of at least 22uF. The capacitor selection should also consider the voltage rating, ripple current rating, and temperature range.
  • The TPS65281-1RGVR can handle an input voltage up to 18V, but it's recommended to operate it within the specified input voltage range of 6.5V to 14V for optimal performance and reliability.
  • The output voltage of the TPS65281-1RGVR can be adjusted by connecting a resistor divider network between the FB pin and the output voltage, and then connecting the center tap of the divider to the VOUT pin. The output voltage can be calculated using the formula: VOUT = 0.8V x (R1 + R2) / R2.
  • The thermal derating curve for the TPS65281-1RGVR is not explicitly provided in the datasheet, but it can be estimated based on the package thermal resistance and the maximum junction temperature. As a general guideline, the device should be derated by 1.5% per degree Celsius above 25°C.
