ISL6265CHRTZ - Renesas Electronics

Description: The ISL6265C is a multi-output controller with embedded gate drivers. A single-phase controller powers the Northbridge (VDDNB) portion of the CPU. The two remaining controller channels can be configured for two-phase or individual single-phase outputs. For uniplane CPU applications, the ISL6265C is configured as a two-phase buck converter. This allows the controller to interleave channels to effectively double the output voltage ripple frequency, and thereby reduce output voltage ripple amplitude with fewer

ISL6265CHRTZ Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the switching components (e.g., FETs, inductors) close to the IC, and use short, wide traces for the power paths. Refer to the application note AN1991 for more details.
  • Use the provided compensation calculator tool or follow the guidelines in the datasheet to determine the optimal compensation network values. The goal is to achieve a stable, high-bandwidth loop with minimal ringing.
  • The maximum allowed input voltage ripple is 1% of the nominal input voltage. Exceeding this limit may affect the regulator's stability and performance.
  • Yes, the ISL6265CHRTZ is rated for operation up to 105°C junction temperature. However, ensure that the PCB and surrounding components can also withstand the high temperature, and consider derating the output current accordingly.
  • Use an oscilloscope to monitor the output voltage, input voltage, and switching node waveforms. Check for proper PCB layout, component selection, and compensation network values. Consult the datasheet and application notes for troubleshooting guidelines.
