RT9059-GQW Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. The RT9059GQW's thermal pad should be connected to the ground plane using multiple thermal vias to ensure efficient heat dissipation.
  • To ensure stability, it's essential to follow the recommended component values and PCB layout guidelines. Additionally, a minimum ESR of 10mΩ for the output capacitor is recommended to prevent oscillations.
  • Although the datasheet specifies a maximum input voltage of 18V, it's recommended to limit the input voltage to 15V to ensure reliable operation and prevent damage to the device.
  • While ceramic capacitors can be used, they may not be the best choice due to their high ESR. A low-ESR electrolytic capacitor or a polymer capacitor is recommended for the output capacitor to ensure stability and low output voltage ripple.
  • The power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout x Efficiency. The efficiency can be estimated from the datasheet's efficiency curve or by measuring the input and output currents and voltages.
