TPS62903RPJR Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the TPS62903RPJR is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • To ensure stability, it's essential to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Additionally, the output capacitor should be placed as close to the output pin as possible.
  • The TPS62903RPJR can deliver up to 3A of output current, but it's recommended to keep it below 2.5A for optimal performance and thermal management.
  • To minimize noise and EMI, it's essential to follow a star-grounding layout, keep the input and output capacitors close to the device, and use a solid ground plane. Additionally, avoid routing sensitive signals near the inductor and use a shielded inductor if possible.
  • The TPS62903RPJR has a thermal derating of 6.4mA/°C above 25°C. This means that for every degree above 25°C, the maximum output current will decrease by 6.4mA. It's essential to consider this derating when designing the system to ensure reliable operation.
