Description

ISL69222IRAZ is an Intersil (now Renesas) voltage‑regulator controller IC from the ISL6922x family. It is used to build buck converters for CPU/GPU core rails in VRMs. The device typically drives high- and low-side MOSFETs in multi‑phase configurations, using current‑mode PWM with programmable switching frequency. It accepts feedback from the output (and may support remote sensing), provides enable/soft‑start, and offers protection features such as overcurrent, overvoltage, undervoltage lockout, and fault/PGOOD signaling. The IR AZ suffix indicates RoHS compliant, tape‑and‑reel packaging; exact pinout and capabilities depend on revision, so consult the datasheet for precise specifications. Common applications include PC motherboards, servers, and other high‑performance DC‑DC power supplies requiring efficient, multi‑phase voltage regulation.

Features

ISL69222IRAZ features (concise):
- Dual/multi-phase PWM controller for CPU/GPU voltage regulation (VRM) with external MOSFET drivers
- Programmable output voltage via resistor dividers; adjustable switching frequency; supports phase interleaving and clock synchronization
- Current-mode control with phase-balancing for multi-phase operation
- Enable input and Power-Good signaling; soft-start and voltage tracking
- Protections: undervoltage lockout (UVLO), overvoltage protection (OVP), overcurrent protection (OCP), thermal/overtemperature protection, and short-circuit protection
- Load-line regulation and feed-forward for stable transient response
- Fault logging/latching and fault outputs
- Monitoring/interface: I2C/SMBus/PMBus-compatible control and readback of voltages, currents, and status
- RoHS-compliant (lead-free) package suitable for VRMs in high-performance systems
Note: Always verify exact numbers (voltage ranges, freq range, packaging) from the latest datasheet for precise specs.

Package

ISL69222IRAZ is in a 28-pin QFN package (5x5 mm, RoHS-compliant).

Pinout

- Pin count: 16 pins (QFN package, ISL69222IRAZ)
- Function: Dual-channel, two-phase synchronous buck regulator controller for CPU VRMs. Provides two PWM outputs to drive external MOSFETs, with current/voltage feedback, reference/VID handling, enable/soft-start, and protection features (UVLO, OVP, etc.).

Manufacturer
