Présentation

Description

ISL6612ACBZ is a dual-channel PWM controller IC from Intersil (now Renesas) used to build CPU-style voltage regulators. It provides two independent (or phase-locked) PWM outputs to drive external MOSFETs for buck or multi‑phase VRMs. Key features typically include current‑mode/voltage‑mode control, programmable switching frequency, soft-start, enable and power‑good signals, feedback via external resistors, and protections such as over‑current, over‑voltage, UVLO, and thermal flags. The ACBZ suffix denotes the package type (an 8‑pin RoHS‑compliant small-outline package). Applications include CPU core voltage rails, GPUs, memory, and other high‑current DC‑DC converters in desktops and embedded systems.

Equivalent

ISL6612ACBZ is a dual-channel multiphase PWM controller for CPU VRMs. Possible equivalents from other vendors include:
- Infineon IR35201 / IR35204 multiphase buck controllers
- ON Semiconductor NCP81239 dual-phase buck controller
- Richtek RT8250 / RT8253 dual- or multiphase controllers
- Anpec APW7159 dual-phase buck controller
Note: pinouts and features differ; verify datasheets for compatibility.

Features

ISL6612ACBZ is a dual-phase, current‑mode PWM controller for multi‑phase buck VRMs. Key features:
- Two PWM channels for multi-phase buck regulators (out‑of‑phase drive to reduce ripple)
- Drives external N‑channel MOSFETs (high-side/low-side)
- Current-mode control with cycle-by-cycle current limit
- Programmable switching frequency; soft-start and tracking
- Enable input and Power-Good output
- Protection: overcurrent, overvoltage, undervoltage, and thermal shutdown
- UVLO with hysteresis
- Adjustable output voltage via feedback network
- Suitable for compact, low‑power VRM applications
- Package: 8-pin (CBZ suffix)
Note: exact frequency range, voltage ranges, and timing details are set by external components per your design.

Pinout

8 pins (8-pin package, e.g., SOIC-8/TSSOP-8).
Function: Dual-channel PWM controller for voltage-regulator modules (VRMs); provides two PWM outputs to drive two MOSFETs in a buck converter, with current-mode control and protection features (enable/FAULT, overcurrent, undervoltage).

Manufacturer

- Manufacturer: Intersil (now a brand of Renesas Electronics Corporation).
- What kind of company: A semiconductor company specializing in analog, mixed-signal, and power-management integrated circuits.

Application

ISL6612ACBZ is a dual PWM/DC-DC buck controller for multi-rail VRMs. Typical applications:
- Desktop/notebook CPU core voltage regulation
- GPU, chipset, and memory voltage rails
- Server/workstation multi-rail power delivery
- FPGA/ASIC voltage rails and development boards
- Embedded/industrial/telecom power supplies requiring tight regulation and sequencing

Package

ISL6612ACBZ uses an 8‑pin surface‑mount package, specifically an SOIC‑8 (D‑8) footprint; Pb‑free variant.
