概要

Description

RT8880CGQW is a Richtek Technology single-channel, synchronous buck regulator IC. It converts a higher input voltage to a stable lower output rail used to power CPUs, GPUs, memory, and other on-board circuits. Key features typically include integrated high-side and low-side MOSFETs (synchronous rectification), current-mode PWM control for fast transient response, and an adjustable output set by an external feedback divider. It provides protection functions such as undervoltage lockout, over-current protection, and over-temperature protection, plus soft-start to limit inrush. The device is designed for compact power-management applications and is packaged in a RoHS-compliant QFN package (code CGQW). External components required generally include an inductor, input/output capacitors, and the feedback network to set Vout (diode may be needed only in certain non-synchronous configurations). For exact pinout, specs, and typical circuits, consult the latest Richtek datasheet.

Pinout

Pin count: 16 pins (QFN package, commonly 3x3 mm).
Function: Dual synchronous buck regulator (dual step-down DC-DC converter) with integrated high-side/low-side MOSFETs for generating two regulated rails in power-management applications.

Manufacturer

- Manufacturer: Richtek Technology Corporation (Richtek).
- What kind of company: A Taiwanese fabless semiconductor company that designs and markets analog and mixed-signal ICs, specializing in power-management ICs (DC-DC converters, regulators, LED drivers, battery chargers, etc.), with manufacturing outsourced to foundries.

Application

RT8880CGQW is a multi-phase, high-current synchronous buck controller used for VRMs and point-of-load DC-DC converters. Typical applications include:
- CPU core and GPU core/memory voltage regulation in desktops, notebooks, and servers
- Motherboard multi-phase VRMs
- Point-of-load regulators for FPGAs/ASICs in telecom and industrial equipment
- High-efficiency DC-DC converters in embedded systems and gaming hardware
(Concise description of its main use as a VRM/POL controller.)

Package

RT8880CGQW is a 16‑pin QFN package (4x4 mm) with an exposed pad.
