ISL95855HRTZ - Renesas Electronics

Description: Compliant with IMVP8™, the ISL95855 provides a complete power solution for Intel microprocessors supporting core, graphics and system agent rails. The controller provides control and protection for three Voltage Regulator (VR) outputs. The VR A output can be configured for 3-, 2- or 1-phase operation. VR B is configurable for 2- or 1-phase operation and VR C supports 1-phase operation. The address options programmable for these three outputs allow for maximum flexibility in support of the IMVP8™ CPU. All th

ISL95855HRTZ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the switching components close to the IC, and use short, wide traces for the power paths. Avoid routing sensitive signals near the switching nodes.
  • Use the datasheet's recommended compensation network values as a starting point. Then, adjust the values based on the specific application's requirements and the desired transient response. You can use simulation tools or empirical methods to fine-tune the compensation network.
  • The maximum allowed input voltage ripple is 10% of the nominal input voltage. Exceeding this limit may affect the regulator's stability and performance.
  • Yes, the ISL95855HRTZ is rated for operation up to 125°C. However, ensure that the PCB and surrounding components are also rated for high-temperature operation. Derate the output current and adjust the thermal design accordingly.
  • Follow good EMC design practices, such as using a shielded enclosure, minimizing loop areas, and using filtering components. Ensure that the PCB layout and component placement minimize radiated emissions and susceptibility to external interference.
