Vue d'ensemble

Description

ISL80101IRAJZ-TK is a Renesas/Intersil DC-DC switching regulator device (ISL80101 family) used to generate a stable low-voltage rail from a higher input in portable and embedded systems. The -TK suffix denotes its packaging/reel variant for manufacturing. It is typically a buck regulator controller (often with a PWM switch driver) that requires external MOSFETs and feedback components to set the output voltage. Key features usually include adjustable output via feedback, fixed switching frequency, soft-start, enable/shutdown, current limit, over-voltage and over-temperature protections, and a power-good signal. The device is applicable to processor, FPGA/ASIC, memory, telecom, and automotive power rails. For precise electrical specs, pinout, layout guidelines, and packaging details, consult the latest ISL80101 datasheet and application notes.

Features

ISL80101IRAJZ-TK is Intersil’s high‑efficiency synchronous buck DC‑DC regulator. Key features typically include:
- Input voltage range: approx. 2.7–5.5 V
- Output: adjustable 0.8–3.6 V (via external resistor network), with fixed options in variants
- Output current: up to about 1 A (typical)
- Switching frequency: around 1 MHz, with PWM/PFM operation
- Synchronous rectification for high efficiency
- Built‑in soft‑start and adjustable startup behavior
- Enable input and Power Good signaling
- Protection: overcurrent/short‑circuit, thermal shutdown, UVLO
- Good regulation accuracy and fast transient response
- Small 8‑pin package, Tape & Reel (TK) option available
Note: exact fixed/adjustable ranges and currents depend on the specific variant; consult the latest datasheet for precise specifications.

Package

QFN (leadless) package with an exposed pad; the “-TK” suffix denotes Tape & Reel variant.

Pinout

- Pin count: 16 pins
- Function: ISL80101IRAJZ-TK is a DC-DC switching regulator controller (buck regulator) device used to generate processor/core voltages. It provides PWM control, oscillator, enable/soft-start, error amplifier inputs, MOSFET gate drive outputs, and protections (overcurrent/overvoltage/thermal) for a switching regulator topology.

Manufacturer

- Manufacturer: Renesas Electronics Corporation (Intersil brand; ISL80101IRAJZ-TK originated from Intersil, now part of Renesas).
- Company type: A global semiconductor company specializing in analog, mixed-signal, and power-management ICs for automotive, industrial, and computing applications.

Application

ISL80101IRAJZ-TK is a high‑efficiency, synchronous buck regulator/controller. Typical applications include:
- Point-of-load VRMs for CPUs/GPUs/FPGA/ASIC cores and memory rails
- Power management for telecom and data-center switches/routers
- Industrial and automotive electronics requiring robust 1.0–3.3 V rails
- Portable/battery-powered devices needing compact DC–DC conversion
- General embedded systems requiring efficient step-down conversion

Equivalent

Direct one-to-one equivalents for ISL80101IRAJZ-TK do not exist. To replace it, choose a buck regulator/controller with matching specs (input range, output, current capability, switching frequency, enable logic, and package). Use distributor cross-reference tools (Digi-Key, Mouser) to find closest matches. Near fits from other vendors include buck controllers in the 1–2 A range, e.g., TI TPSxxx, Analog Devices ADP/ADPxxx, Richtek RTxxx families, depending on pinout and thermal requirements.
