Descripción general

Description

ISL95831IRTZ is a multi-rail, multi‑phase buck regulator controller from Intersil (now Renesas) used for CPU/core and memory voltage regulation in notebooks and compact systems. It acts as the control engine for several synchronous buck stages, delivering precise, programmable output voltages across multiple rails. Key features typically include multi-phase PWM control, programmable output voltage (often via VID or digital interface), current‑limit and over‑current protection, over‑temperature protection, and fault/status reporting. The IRTZ suffix denotes a specific RoHS-compliant package variant (package type/lead-free packaging) used for this device. For exact mechanical details (pin count, package size) and electrical specs (input range, max current, number of usable phases, control interface), consult the latest ISL95831 datasheet and hardware user guide.

Features

ISL95831IRTZ features (high-level):
- High-performance multi-phase buck regulator controller for CPU/GPU VRMs
- 3-phase synchronous operation to support high output current
- Programmable switching frequency for efficiency/transient performance
- Voltage-mode control with fast transient response
- External MOSFET gate drive (controller provides gate signals)
- Adjustable output voltage via feedback divider; supports sequencing/tracking
- Phase balancing for even current sharing across phases
- Protections: over-current/short-circuit, over-voltage, under-voltage, thermal shutdown
- Soft-start and enable control; fault reporting
- Remote sense/feedback for accurate regulation
- Small RoHS-compliant package suitable for VRM applications
Note: exact electrical specs (ranges, mating package, timing) are in the datasheet; verify for your design.

Package

ISL95831IRTZ is in a 16‑pin TSSOP package (TSSOP-16), RoHS-compliant and available in Tape & Reel.

Pinout

- Pin count: 28 pins (ISL95831IRTZ in its 28-pin package)
- Function: Multi-phase PWM buck regulator controller. It generates drive signals for external MOSFETs (high-side/low-side) to regulate output voltage via feedback from the output, with features like current-mode control, soft-start, enable, and protection (OC/short-circuit, etc.).

Manufacturer

Manufacturer: Renesas Electronics (Intersil). Intersil is a semiconductor company that designs and manufactures analog, mixed-signal, and power-management integrated circuits, serving markets such as computer, communications, automotive, and consumer electronics.

Application
