概述

Description

ISL95808IRZ-T is an Intersil/Renesas multi-rail, multi-phase buck controller used for CPU/GPU VRMs. It implements IMVP8-compatible regulation with up to eight PWM phases to drive external MOSFETs, typically via an I2C (VID) interface for voltage programming and dynamic scaling. Key features include cycle-by-cycle overcurrent/overvoltage protection, thermal shutdown, fault reporting, load-line calibration, soft-start, and rail sequencing. It offers programmable switching frequency, phase balancing, and multi-rail supervision for safe startup and shutdown. The IRZ-T package is a RoHS-compliant surface-mount package suitable for motherboard, notebook, and server VRMs. Typical applications: CPU core and memory power rails, GPU rails, and other high-current VRMs in desktops, laptops, and servers.

Features

ISL95808IRZ-T features (concise):
- 8-channel, multi-rail buck regulator/controller (synchronous) with I2C control
- Independent programmable VOUT per channel; sequencing, tracking, and remote sensing
- Interleaved phase operation with automatic current balancing
- Programmable switching frequency with clock synchronization option
- Soft-start, programmable ramp, margining, and power-good signaling
- Enable/disable control and fault masking
- Protections: UVLO, OVP, OCP/short-circuit, OTP/thermal shutdown
- Monitoring: VOUT, IMON, die temperature, fault/status flags
- Packaging: ISL95808IRZ-T in IRZ (32-pin QFN); -T denotes tape-and-reel
Applications: CPU/GPU/memory VRMs and other multi-rail power systems.

Package

ISL95808IRZ-T uses a QFN package: 7×7 mm, 48-lead (QFN-48). The -T suffix indicates Tape & Reel packaging.

Pinout

Pin count: 8 pins (IRZ package).
Function: An 8‑pin buck regulator PWM controller (VRM/controller) used to drive external MOSFETs for CPU core/voltage regulation, providing current‑mode PWM, feedback, enable, and protection features.

Manufacturer

Manufacturer: Intersil (ISL prefix). Intersil is a semiconductor company specializing in analog, mixed-signal, and power-management ICs; it is now part of Renesas Electronics.

Application

ISL95808IRZ-T is a multi‑phase, high‑current buck controller for VRMs. Typical applications: CPU/GPU core voltage regulators (desktops/servers/laptops); memory and chipset power rails; VRMs for FPGAs/ASICs and graphics cards; motherboard power regulators and other high‑current point‑of‑load regulators in telecom/industrial equipment.
