ISL62773IRZ - Renesas Electronics

Description: The ISL62773 is fully compliant with AMD Fusion™ SVI 2. 0 and provides a complete solution for desktop microprocessor and graphics processor core power. The ISL62773 controller supports two Voltage Regulators (VRs) with three integrated gate drivers and two optional external drivers for maximum flexibility. The Core VR can be configured for 3-, 2-, or 1-phase operation while the Northbridge VR supports 2- or 1-phase configurations. The two VRs share a serial control bus to communicate with the AMD CPU and a

ISL62773IRZ Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note AN1995, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
  • The selection of the inductor depends on the output current, output voltage, and switching frequency. Renesas provides an inductor selection guide in their application note AN1995, which includes a list of recommended inductors and their corresponding characteristics.
  • The maximum junction temperature (Tj) for the ISL62773IRZ is 125°C, as specified in the datasheet. However, it's recommended to keep the junction temperature below 100°C for optimal reliability and performance.
  • While the ISL62773IRZ can operate up to 125°C, it's essential to consider the thermal management and derating of the device for high-temperature applications. Renesas provides thermal derating curves in the datasheet to help with this calculation.
  • Renesas provides EMC guidelines in their application note AN1995, which includes recommendations for PCB layout, component selection, and shielding to minimize electromagnetic interference (EMI) and ensure compliance with EMC standards.
