Overview

Description

ISL6753AAZA is an Intersil (Renesas) multiphase PWM/buck controller used to regulate CPU/GPU core rails. It drives external high- and low-side MOSFETs in a synchronous buck converter, delivering precise voltage regulation and fast transient response.
Key points:
- Multiphase operation (2–3 phases typical) for high current applications
- Programmable switching frequency and voltage regulation
- Phase current sharing, soft-start, and enable control
- Protection and diagnostics: overcurrent/overvoltage/undervoltage, fault reporting
- Designed for VRMs in CPUs, GPUs, servers, and high‑end power supplies
- AAZA denotes a specific packaging/temperature variant; exact pinout and specs are in the datasheet
If you want, I can summarize the exact electrical specs (input range, reference voltage, clamp levels, timing) from the datasheet or help you compare it to similar VRM controllers.

Features

ISL6753AAZA is a multi‑phase buck controller intended for VRMs (CPU/GPU power rails). Key features (typical for ISL6753 family; verify exact variant in the datasheet) include:
- Wide input range and robust protection (UVLO, overvoltage, overcurrent/short-circuit, overtemperature)
- Current‑mode control with slope compensation for stable multiphase operation
- Programmable switching frequency to balance efficiency and EMI
- Multiphase interleaved regulation with shared feedback and per‑phase outputs
- Programmable output voltage via error amplifier and reference
- Soft‑start, enable/shutdown, and fault/status reporting
- Gate‑drive outputs to external MOSFETs (requires external high/low side drivers)
- Optional synchronization/phase alignment and remote sense feedback
Note: exact feature set and pinout depend on the AAZA variant; consult the latest datasheet for precise specifications and package options.

Package

ISL6753AAZA is offered in a 32‑pin QFN package with an exposed pad (no-lead).

Pinout

Pin count: 28 pins (28-pin QFN).
Function: Dual-channel synchronous buck regulator controller for VRMs (CPU core power). It generates gate-drive signals for external MOSFETs, uses current-sense and voltage-feedback inputs for regulation, and includes features such as soft-start, enable control, and protection (current/overload).

Manufacturer

- Manufacturer: Renesas Electronics Corporation (Intersil brand)
- Company type: A Japanese multinational semiconductor company specializing in analog, mixed‑signal, and power‑management ICs for automotive, industrial, and consumer electronics.

Application

ISL6753AAZA is a multi-phase PWM controller/driver for high-efficiency synchronous DC-DC converters. Applications: CPU/GPU VRMs, server and telecom power supplies, point-of-load regulators for embedded/industrial systems, and other multi-phase buck converters in data centers and consumer electronics.
