概述

Description

RT8880CGQW is a RichTek power-management IC, specifically a high-efficiency synchronous buck (step-down) regulator in a compact QFN package. It integrates the high-side and low-side MOSFETs and provides a configurable DC-DC output for supplying low-voltage rails in portable and embedded electronics. Key features typically include current-mode control, adjustable output via a feedback network, enable and power-good signals, and protection functions (overcurrent, thermal shutdown, undervoltage lockout). It’s aimed at small-form-factor power supplies for smartphones, tablets, wearables, embedded systems, and other consumer electronics. For exact electrical specs, pinout, and application circuit, consult the official RT8880CGQW datasheet. If you want, I can fetch or summarize the precise parameters.

Package

RT8880CGQW uses a QFN package — 16 pins, typical footprint about 4×4 mm (lead-free).

Pinout

- Pin count: 28 pins (QFN-28 package).
- Function: Richtek RT8880CGQW is a dual synchronous buck regulator/controller with integrated power MOSFETs, used for multi-rail voltage regulation (VRM) in switching power supplies.

Manufacturer

- Manufacturer: Richtek Technology Corporation (Richtek).
- What kind of company: A Taiwan-based fabless semiconductor company that designs and markets analog and mixed-signal power-management ICs (PMICs, DC-DC regulators, LED drivers, battery chargers) and outsources manufacturing to foundries.

Application

Applications: Multi-phase synchronous buck controller for VRMs in PCs/servers. Used for CPU core and GPU power regulation, memory and chipset rails, and other DC-DC power rails. Suitable for desktops, notebooks, graphics cards, and telecom/industrial power modules.
