概述

Description

ISL68137IRAZ-T is a Renesas Intersil multi-phase buck regulator controller designed for CPU/GPU and other high‑current VRMs. It drives external high‑side and low‑side MOSFETs in a multi‑phase configuration to generate one or more low-voltage rails from a higher input.
Key points:
- Multi‑phase, phase‑interleaved PWM controller with current‑mode control and per‑phase drive
- Programmable switching frequency, adjustable output voltages, and multi‑rail sequencing
- Remote sense, feedback (VFB), and external compensation for accurate regulation
- Protection features: overcurrent/short‑circuit, over/under voltage, undervoltage lockout, thermal shutdown
- Soft‑start, enable/shutdown control, and fault reporting
Requires external components: MOSFETs, inductors, sense resistors, passives, and bootstrap network. The -T suffix denotes tape‑and‑reel packaging (with RoHS compliance). Typical applications include VRMs for CPUs/GPUs, servers, workstations, and other high‑current, multi‑rail power stages.

Features

Key features of ISL68137IRAZ-T (VRM controller):
- Multiphase (3- or 4-phase) PWM controller for CPU/GPU core voltage rails
- Synchronous buck gate-drive outputs for high efficiency
- Current-mode control with slope compensation for high-current stability
- Programmable switching frequency
- Programmable output voltage via feedback network (adjustable Vcore range)
- Remote sense and regulation droop compensation
- Robust protection: overcurrent/short-circuit, overvoltage, undervoltage, and thermal shutdown
- Enable/soft-start and fault/status reporting for reliable sequencing
Note: For exact specifications, recommended operating ranges, and pinout, please refer to the official datasheet.

Package

ISL68137IRAZ-T uses a 32‑lead QFN package (5×5 mm). The “-T” indicates Tape & Reel.

Pinout

Pin count: 32 pins (LQFP-32 package).
Function: High-performance multiphase PWM/controller for CPU voltage regulator modules (VRMs). It provides the control signals for external MOSFETs to implement multi‑phase buck converters, with programmable switching frequency, soft‑start, current/voltage feedback, and related VRM regulation features.

Manufacturer

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

Application

Applications:
- Multi‑phase VRM controller for CPU/GPU core rails
- Server/workstation motherboards (multi‑phase VRMs)
- Data center power delivery for AI accelerators (FPGA/ASIC)
- Telecom and networking equipment
- Embedded/industrial point‑of‑load regulators

Equivalent

Direct equivalents aren’t published. The closest cross-references are other Renesas/Intersil parts in the ISL6813x/ISL6814x multiphase buck controller family. For third‑party substitutes, use distributor cross‑reference tools (Digi‑Key, Mouser) to find functionally similar multiphase controllers (e.g., Analog Devices LTC389x or TI multiphase controllers); none are pin‑for‑pin drop‑in—verify Vin, Vout rails, number of phases, timing, and package.
