Overview

Description

ISL68223IRAZ-T is Intersil (Renesas) multi‑phase PWM controller for voltage regulator modules (VRMs). It drives external MOSFETs to form a multiphase buck converter used to regulate CPU core/memory rails with high efficiency and fast transient response.
Key points:
- Supports interleaved multi‑phase operation for robust, high‑current VRMs.
- Programmable switching frequency and adjustable output voltage via an external feedback network.
- Built‑in protections: soft‑start, enable/disable, overcurrent (current limit), undervoltage/overvoltage, and remote sensing options.
- Intended for use with external N‑channel MOSFETs and standard VRM components in CPUs, GPUs, servers, and high‑end embedded systems.
Package note:
- -T denotes tape-and-reel delivery; -IRA Z indicates RoHS-compliant packaging style.

Features

ISL68223IRAZ-T is a digital multi‑phase VRM controller. Key features include:
- PMBus/I2C digital control and monitoring
- Supports up to four synchronous buck phases with phase balancing
- Programmable switching frequency
- Adjustable output voltage with remote sensing
- Load-line adjustment and current sharing between phases
- Soft-start/soft-stop control
- Comprehensive protections: UVLO, OVP, OCP/overcurrent, thermal shutdown
- Fault reporting with latch/clear and status outputs
- Monitoring: Vout, Vin, phase currents, temperature
- Small footprint packaging option (IRAZ-T)
Note: Values (frequency ranges, voltage limits) are programmable via the PMBus register map.

Package

Quad Flat No-Lead (QFN) package, 32-pin, 5×5 mm (IRAZ variant), supplied on Tape & Reel.

Pinout

- Pin count: 28 pins (28-pin package)
- Function: Multi‑phase PWM buck controller for DC‑DC VRMs (CPU core voltage). Provides oscillator, error amplifier inputs, and PWM outputs to drive external MOSFETs for multi‑phase voltage regulation, with protections (soft‑start, overcurrent/OV).
