Overview

Description

Introduction to RT6190GQW:
- A RichTek synchronous buck DC-DC converter in a QFN package.
- Integrates high-side and low-side MOSFETs for high-efficiency step-down regulation.
- Adjustable output with external feedback resistors; supports programmable switching frequency; includes soft-start and an enable pin.
- Protections: undervoltage lockout, over-current, over-temperature, and short-circuit protection.
- Suitable for compact power rails in portable/consumer devices (APs, memory, PMICs, CPU/GPU rails).
Usage notes:
- Requires external input/output capacitors and a feedback network; follow layout guidelines to minimize noise.
Important:
- For exact electrical characteristics (input range, Vout range, max current, switching frequency, pinout, package details), consult the official RT6190GQW datasheet from RichTek.

Package

RT6190GQW is in a QFN package—16-pin, 4.0 x 4.0 mm, with wettable flanks.

Pinout

- Pin count: 16-pin QFN (GQW package)
- Function: Single-channel buck (step-down) DC-DC regulator with an integrated switching MOSFET, supporting feedback (FB), enable (EN), input (VIN), ground (GND), switching node (LX), and bootstrap/gate-drive pins (BST/BOOT) for regulation.

Manufacturer

- Manufacturer: Richtek Technology Corporation (Richtek).
- What kind of company: A Taiwan-based fabless semiconductor company specializing in analog and power-management ICs (PMICs), such as DC-DC converters, regulators, LED drivers, and related power-management solutions.

Application

RT6190GQW is a high‑efficiency synchronous buck regulator. Typical applications include:
- Battery-powered portable devices (smartphones, tablets, wearables) for core rails
- Notebooks/ultrabooks
- Embedded systems and IoT
- Consumer electronics (TVs, set‑top boxes, AV gear)
- Computer motherboards (CPU/GPU/memory rails)
- Automotive infotainment and sensor systems requiring robust DC‑DC conversion
