概要

Description

ISL80113IRAJZ is a DC-DC switching regulator IC from Renesas Intersil. It’s designed to generate one or more low-voltage rails from a higher input supply, typically using integrated high-side/low-side MOSFETs for high efficiency. The device features adjustable output voltages via external feedback, a fast current‑mode PWM control, soft-start, enable control, and a power-good signal. It also includes protections such as undervoltage lockout, overcurrent/short-circuit protection, overvoltage protection, and thermal shutdown. The IR AJZ suffix indicates the packaging/temperature/lead finish variant. This part is commonly used to power core rails for processors, memories, FPGAs, and other components in telecom, computing, and industrial equipment. For exact specs (input range, max output current, output voltage options, pinout, and package), consult the official datasheet and application notes.

Features

ISL80113IRAJZ is Intersil’s single-channel DC-DC regulator (step-down) in an 8-pin package. Key features:
- Wide input voltage range suitable for battery and low-voltage rails
- Adjustable output via external feedback network
- High efficiency with PWM/PFM operation for light-load efficiency
- Soft-start to limit inrush and improve output stability
- Enable/shutdown control for power sequencing
- Protections: undervoltage lockout, overcurrent/short-circuit protection, thermal shutdown (and fault protection)
- Low quiescent current in light-load modes
- Small footprint package (IRAJZ 8-pin)
Applications: portable devices, embedded systems, battery-powered equipment, and other low-voltage regulation needs.

Package

ISL80113IRAJZ is in an 8-pin DFN/QFN package (3×3 mm) with an exposed pad.

Pinout

I don’t have the exact pinout for ISL80113IRAJZ without the specific datasheet/package. Pin count and function vary by package (e.g., TSSOP, QFN). Please share a link to the datasheet or confirm the exact package (e.g., 16-pin, 20-pin, etc.). The ISL80113 family are DC-DC regulator/controllers (high-efficiency buck regulators with/without integrated FETs), but I need the correct package to state the exact pin count and individual pin functions.

Manufacturer

- Manufacturer: Renesas Electronics Corporation (the Intersil brand is now part of Renesas).
- Kind of company: A Japanese multinational semiconductor company that designs and manufactures analog, mixed-signal, and power integrated circuits.

Application

ISL80113IRAJZ is a high-efficiency multi-output DC-DC regulator. Common applications include POL power for CPUs/GPUs, FPGA/ASIC cores, and other multi-rail power systems in servers, data centers, networking/telecom equipment, and automotive/industrial electronics where compact, efficient conversion to multiple rails is needed.
