Descripción general

Description

ISL81487LIBZ-T is a high-performance switching regulator controller from Intersil (now Renesas) used to build multiphase buck VRMs. It provides the PWM control and feedback sensing needed to regulate a CPU/GPU power rail when paired with external MOSFETs and inductors. Key points:
- External MOSFET driver for a buck converter (no integrated MOSFETs).
- Programmable switching frequency and phase interleaving for multi-phase operation.
- Feedback-driven output regulation with soft-start.
- Protection features: overcurrent/short-circuit, overvoltage/undervoltage, thermal/enable fault handling.
- Diagnostic/status outputs and fault reporting.
- Suitable for high-current, low-voltage rails in processors, GPUs, and high-performance power modules.
- LIBZ-T denotes a specific RoHS-compliant package variant of the part.
For exact electrical specs, pinout, operating ranges, and application notes, consult the ISL81487 datasheet and the package guide.

Features

I don’t have the exact datasheet here, but ISL81487LIBZ-T is a Renesas/Intersil PWM controller. Typical features (from the ISL81487 family) include:
- Dual/interleaved PWM controller for high-current DC-DC applications
- Requires external MOSFETs (not a fully integrated FET device)
- Programmable switching frequency with optional synchronization
- Adjustable output voltage via feedback resistor network
- Soft-start and error amplification for controlled ramp
- Overcurrent/short-circuit protection and current limiting
- Overvoltage protection and UVLO (undervoltage lockout)
- Thermal shutdown/thermal warning
- Enable/Run input
- Gate-drive bootstrap for high-side drive
- Status/FAULT reporting pins
- External compensation and flexibility for various topologies
- Pb-free LIBZ-T package; suitable for -40°C to around 125°C (per datasheet)
Note: exact electrical specs (voltage ranges, current ratings, timing, etc.) should be confirmed from the official datasheet for the LIBZ-T variant.

Package

ISL81487LIBZ-T uses an 8-pin SOIC (Small-Outline) package.

Pinout

Pin count: 16 pins. Function: Isolated switching regulator controller for DC-DC power supplies (flyback topology), providing PWM regulation with galvanic isolation between input and output.

Manufacturer

- Manufacturer: Renesas Electronics Corporation (Intersil brand; ISL prefix comes from the former Intersil line).
- Company type: A Japanese multinational semiconductor company that designs and manufactures analog, mixed-signal, and power-management ICs for automotive, industrial, and consumer markets.

Application

Typical applications: isolated power supplies and DC-DC converters (flyback/forward) for telecom, data center, networking, industrial control, automotive and medical electronics; point-of-load isolated rails; and any system requiring galvanic isolation between primary and secondary sides (offline/AC-DC adapters and power modules).
