概述

Description

ISL68137IRAZ is a high-performance multiphase PWM controller IC from Intersil (Renesas) used to regulate low-voltage rails in VRMs.
- What it does: controls external MOSFETs in a multi-phase buck converter to generate CPU/GPU core voltages.
- Key features: multi-phase interleaving, current-mode control, programmable switching frequency, soft-start, enable/shutdown, remote sense, and protection (overcurrent, overvoltage, undervoltage, etc.).
- Packaging: IR AZ denotes the RoHS-compliant, lead-free variant; consult the datasheet for pinout.
- Applications: CPU/GPU voltage regulation in desktops/servers, high-efficiency DC-DC converters, and similar VRM needs.
Note: Always refer to the latest datasheet for exact electrical characteristics and recommended operating conditions.

Features

ISL68137IRAZ is a multi-rail, multiphase buck regulator controller from Intersil (Renesas). Key features typically include:
- Multi-phase gate-drive controller for external MOSFETs (flexible phase configuration)
- Programmable switching frequency; supports spread-spectrum
- Analog/peak-current mode PWM with slope compensation
- Soft-start and output-voltage sequencing
- Enable input and fault/status reporting
- Regulation with feedback loop (voltage regulation across rails)
- Overcurrent (cycle-by-cycle) protection and short-circuit protection
- Overvoltage and undervoltage protection; UVLO
- Thermal shutdown protection
- Suitable for CPU core/mVRM-style applications
- Lead-free, RoHS-compliant package (IRAZ)
Note: exact phase count, pinout, input voltage range, and interface details are in the official datasheet.
