RT7299BHGQW Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the switching node (SW) away from sensitive analog nodes, and use a thermal relief pattern under the IC to improve heat dissipation.
  • Use a high-precision voltage reference, such as a 0.5% resistor divider network, and ensure the feedback resistors are 1% or better. Also, minimize the distance between the output capacitor and the feedback pin to reduce noise.
  • Although the datasheet specifies a maximum input voltage of 28V, it's recommended to limit the input voltage to 24V to ensure reliable operation and prevent damage to the internal regulator.
  • Use a shielded inductor, add a common-mode choke, and ensure the PCB layout follows good EMI design practices. Additionally, consider adding EMI filters or ferrite beads on the input and output lines.
  • Use a low-ESR ceramic capacitor (e.g., X5R or X7R) with a value of 10uF to 22uF, depending on the input voltage and current requirements. Ensure the capacitor is rated for the maximum input voltage.
