Description

ISL6208CBZ is a dual-channel PWM controller for DC-DC voltage regulation (VRMs) from Intersil/Renesas. It provides two independent current-mode control loops that drive external N‑channel MOSFETs in a synchronous buck arrangement, enabling single- or multi‑phase converters to generate CPU/GPU core voltages. Key features include programmable switching frequency, soft-start, enable, remote feedback (VFB), and protections such as overcurrent, overvoltage, short-circuit, and thermal shutdown. It requires external MOSFETs, inductor, input/output capacitors, sense resistors, and feedback components. Applications include VRMs for CPUs, GPUs, FPGAs, DSPs in desktops, servers, and embedded systems. The CBZ suffix denotes a package variant; check the datasheet for exact pinout, electrical specs, and application notes.

Features

ISL6208CBZ features (concise):
- Dual-channel, 2-phase interleaved PWM controller for multiphase buck regulators (CPU VRMs).
- Programmable switching frequency over a wide range to optimize efficiency.
- Current-mode control with slope compensation for stable high-current operation.
- Adjustable deadtime and soft-start (with optional tracking).
- Flexible feedback options (direct/remote sense) and programmable output voltage.
- Protection: undervoltage lockout, overvoltage protection, cycle-by-cycle current limit, thermal shutdown.
- Enable input and Power-Good signal for sequencing and fault indication.
- Gate-drive outputs for external N-channel MOSFETs (with bootstrap supply).
- Fault reporting/status pins and configurable fault handling.
- Suitable for multi-phase, high-current designs requiring accurate regulation and protection.

Package

ISL6208CBZ comes in an 8-pin small-outline package (SOIC-8), RoHS-compliant.

Pinout

- Pin count: 8 pins (CBZ package, SOIC-8 style)
- Function: Dual-channel PWM controller for a switching regulator (VRM). It provides two PWM outputs to drive a multiphase buck converter, with built-in reference, oscillator, two error amplifiers, soft-start, current-limit/shutdown protection, and related feedback functions.

Manufacturer

- Manufacturer: Intersil (the ISL6208CBZ product; Intersil is now part of Renesas Electronics).
- What kind of company: A semiconductor company specializing in analog, power-management, and mixed-signal integrated circuits. Renesas acquired Intersil in 2017, and Intersil operates as part of Renesas.

Application

ISL6208CBZ is a dual, two‑phase PWM buck controller suitable for VRMs and other point‑of‑load DC‑DC converters. Common applications: CPU core and GPU voltage regulators in desktops and notebooks, motherboard VRMs, server/telecom DC‑DC power modules, and embedded systems requiring external MOSFETs and high‑efficiency 2‑phase buck regulation.
