ISL6366CRZ-T

ISL6366CRZ-T is a Renesas/Intersil high-performance buck regulator controller (multi-phase) used to build CPU/GPU voltage-regulation modules (VRMs). It is not a regulator by itself; external MOSFETs, sense resistors, and passive components are required.
Key points:
- Function: current-mode PWM controller for multiphase synchronous buck converters; drives external high-side/low-side MOSFETs.
- Features: programmable switching frequency, adjustable output voltage, remote sense, phase-sharing support, and protections (UVLO, overcurrent/overvoltage/thermal).
- Package/grade: the CRZ-T suffix indicates a specific package type and temperature grade per Renesas packaging naming.
- Applications: VRMs in desktops, servers, or other systems requiring multi-phase core or memory voltage rails.
For exact electrical specs and pinout, consult the official datasheet.

- Pin count: 28 pins (QFN package, CRZ).
- Function: Multi‑phase buck regulator controller used for CPU/GPU VRMs; provides high‑speed, current‑mode PWM control and drives external MOSFETs (high‑ and low‑side) with features for phase interleaving, synchronization, and voltage monitoring.

Manufacturer: Renesas Electronics Corporation (Intersil). Intersil was a U.S.-based semiconductor company that specialized in analog and power-management ICs; it is now a wholly owned subsidiary of Renesas Electronics.

ISL6366CRZ-T is a multi‑phase, synchronous buck controller used for VRMs. Typical application areas include:
- CPU/GPU core voltage regulation in servers, workstations, desktops
- VRMs for FPGAs, ASIC accelerators, and memory subsystems
- Point‑of‑load (POL) power in data centers and telecom/network equipment
- Industrial and embedded systems requiring high‑efficiency DC‑DC conversion

ISL6366CRZ-T comes in an 8-pin SOIC (RZ) leaded package, RoHS-compliant, available in Tape-and-Reel packaging.
