Overview

Description

ISL8500IRZ is a voltage-regulator controller IC from Intersil (now Renesas) used to build high-efficiency multiphase buck regulators. It provides the control logic for a VRM, driving external MOSFETs to regulate CPU/core or other high-current rails. Key points:
- Multiphase support for high current and good transient response
- Voltage-mode/linear-like PWM control with programmable switching frequency
- Feedback-driven output voltage with soft-start and enable/shutdown
- Protection features such as undervoltage, overcurrent/overvoltage, and fault handling
- Requires external MOSFETs and passive components to complete the regulator
Packages: IRZ (specific Intersil/Renesas package code)
Typical uses: motherboard CPU/graphics power rails, servers, and other embedded power supplies requiring precise, efficient regulation.
Note: Check the latest datasheet for exact electrical specs, default configurations, and the number of controllable phases for your design.

Package

ISL8500IRZ is in an 8-pin surface-mount package—specifically an 8‑pin SOIC package.

Pinout

- Pin count: 16 pins (IRZ package)
- Function: Dual buck regulator controller (two-channel PWM DC-DC converter; drives external MOSFETs to regulate output voltages).

Manufacturer

- Manufacturer: Renesas Electronics Corporation (the Intersil brand; ISL prefixes come from Intersil, now part of Renesas).
- Company type: Japanese multinational semiconductor company that designs and manufactures analog, power management, microcontroller, and other ICs for global markets.

Application

ISL8500IRZ is a multi-phase PWM controller for VRMs. Typical applications:
- CPU core voltage regulation (desktop/servers)
- GPU/memory VRMs
- FPGA/ASIC power supplies
- Telecom/network equipment switching regulators
- Notebook and embedded system point-of-load regulators
Designed for high-current, tight transient response in multi-rail DC-DC converters.
