TPS3435CAIEGDDFR Frequently Asked Questions (FAQs)

  • A good PCB layout is crucial for the TPS3435CAIEGDDFR. TI recommends a 4-layer board with a solid ground plane, and the IC should be placed near the input capacitors. Keep the input and output traces short and separate to minimize noise and EMI. Refer to the TI application note SLVAE03 for more details.
  • Choose input capacitors with low ESR (Equivalent Series Resistance) and high ripple current rating. For output capacitors, select ones with low ESR and high capacitance. The recommended values are 10uF to 22uF for input and 22uF to 47uF for output. Refer to the datasheet for more information on capacitor selection.
  • The TPS3435CAIEGDDFR can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and minimize power dissipation.
  • The output voltage can be adjusted by changing the resistor divider network (R1 and R2) connected to the FB pin. Use the formula Vout = 0.8V x (1 + R2/R1) to calculate the desired output voltage. Make sure to choose resistors with low tolerance and high precision.
  • The TPS3435CAIEGDDFR has a thermal derating of 30°C/W. This means that for every 1W of power dissipation, the junction temperature will increase by 30°C. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.
