概述

Description

ISL6612ACBZ is a dual-channel PWM controller designed for multiphase synchronous buck regulators used in CPU core VRMs. It does not include MOSFETs; you pair it with external N-channel MOSFETs and a driver stage to regulate the output voltage. It generates complementary gate signals for high- and low-side FETs, using feedback from the regulated output to adjust duty cycle. Typical features include two error amplifiers, an internal reference, adjustable switching frequency, programmable output voltage via resistor networks, soft-start, enable/UVLO, current balancing (phase interleaving), and optional spread-spectrum. It supports multiphase interleaving for improved transient response and reduced ripple. Packages include CBZ variants. Applications are VRMs in desktop/server motherboards, GPUs, and embedded boards. For exact specs (Vref, frequency range, pinout, external components), consult the datasheet.

Features

ISL6612ACBZ features (concise):
- Dual-channel, interleaved PWM controller for multi-phase VRMs (e.g., CPU core power)
- Two PWM outputs for two-phase buck conversion with programmable phase/dead-time
- Voltage-mode or current-mode control with slope compensation
- Two error amplifiers with external compensation network
- Programmable switching frequency and soft-start; enable input and Power-Good (PGOOD)
- Protections: UVLO, OVP, OCP/short-circuit, over-temperature with latch
- Fault detection/recovery and robust protection for gaming CPU/RAM rails
- Pb-free, RoHS-compliant package (ACBZ)
Note: Detailed electrical characteristics (e.g., exact frequency range, sense inputs) are in the datasheet.

Package

QFN (leadless) package.

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOIC-8/TSSOP-8).
- Function: Dual-channel PWM buck regulator controller used to drive external MOSFETs for a multiphase CPU core voltage regulator (two PWM outputs, oscillator/reference, enable and protection features).

Manufacturer

- Manufacturer: Intersil (a semiconductor company, now part of Renesas Electronics). The ISL6612ACBZ uses the Intersil/ Renesas branding.
- What kind of company: A designer/manufacturer of analog and mixed-signal integrated circuits, specializing in power-management ICs (voltage regulators, controllers, drivers) and related ICs.
