ISL6333AIRZ - Renesas Electronics

Description: The ISL6333 three-phase PWM family of control ICs provide a precision voltage regulation system for advanced microprocessors. The integration of power MOSFET drivers into the controller IC marks a departure from the separate PWM controller and driver configuration of previous multi-phase product families. By reducing the number of external parts, this integration is optimized for a cost and space saving power management solution. The ISL6333 controllers are designed to be compatible with Intel VR11. 1 Appli

ISL6333AIRZ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power paths. Avoid routing sensitive signals near the inductor.
  • Choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value (e.g., 1-2.2 μH). Consider the inductor's physical size, core material, and operating frequency when selecting an inductor.
  • The ISL6333AIRZ can handle input voltages up to 28V, but the recommended maximum input voltage is 24V to ensure reliable operation and minimize stress on the internal components.
  • The output voltage can be adjusted by changing the resistor divider ratio (R1 and R2) connected to the FB pin. Use the formula: Vout = 0.8V x (1 + R2/R1) to calculate the desired output voltage.
  • The EN (enable) pin is used to turn the converter on or off. When EN is high, the converter is enabled, and when EN is low, the converter is disabled and enters a low-power shutdown mode.
