FAQs

What is ISL6537CRZ?

The ISL6537CRZ is a dual-channel multi-phase PWM controller designed by Intersil, which is now a part of Renesas Electronics Corporation. It is designed for high-performance power management applications, such as voltage regulation for CPU and GPU power supplies in desktop PCs, servers, and high-end workstations.

How Does ISL6537CRZ Work?

The ISL6537CRZ works by controlling the power delivery to the CPU and GPU through a multi-phase PWM (Pulse Width Modulation) architecture. It regulates the output voltage by adjusting the duty cycle of the PWM signals, ensuring efficient and stable power delivery to the load. The controller features programmable switching frequency, current monitoring, and overcurrent protection to optimize performance and reliability.

How Many Pins does ISL6537CRZ have and What are the Functions of the Pinout Configuration?

The ISL6537CRZ is housed in a 32-lead QFN (Quad Flat No-leads) package. The pinout configuration includes:

  • BOOT0, BOOT1: Bootstrap supply pins for high-side gate drivers.
  • CSS1, CSS2: Current sense inputs for phase 1 and phase 2.
  • FB1, FB2: Feedback inputs for phase 1 and phase 2.
  • PHASE1, PHASE2: Phase signals for phase 1 and phase 2.
  • VCC, VCCP: Controller power supply and power supply input for synchronous buck driver.
  • VID4, VID5: Voltage identification inputs for dynamic VID (Voltage ID) changes.
  • PGOOD1, PGOOD2: Power good outputs for phase 1 and phase 2.

What are the Pros and Cons of ISL6537CRZ?

Pros:

  • Multi-Phase Operation: Enables efficient power delivery and thermal management in high-performance systems.
  • Programmable Features: Offers flexibility through programmable switching frequency and dynamic VID support.
  • Current Monitoring: Provides accurate current sensing for system protection and optimization.
  • Integrated Protection: Includes overcurrent protection and thermal shutdown for enhanced reliability.
  • Compact Package: The QFN package provides space-efficient integration in compact designs.

Cons:

  • Complex Configuration: Requires careful design and configuration for optimal multi-phase operation.
  • External Components: May require additional external components such as MOSFETs and inductors for complete power supply implementation.

Are There Any Equivalents/Alternatives to ISL6537CRZ for Recommendation?

  • The IR35201 from Infineon Technologies is a similar dual-phase PWM controller for CPU and GPU power supplies.
  • Alternatives to the ISL6537CRZ include the MAX17060 from Maxim Integrated and the UP6161AQ from uPI Semiconductor.
