Overview

Description

RT9519BGQW is a RichTek DC-DC regulator IC (a synchronous buck regulator) in a QFN package. It integrates high- and low-side MOSFETs and is used to generate low-voltage rails from a higher input for electronics such as notebooks, embedded systems, and automotive/industrial apps.
Key points:
- Type: synchronous buck converter with external feedback for adjustable output.
- Features: enable/shutdown, soft-start, overcurrent/short-circuit protection, thermal/overload protection, and typical protection options (e.g., OVP/OTP depending on variant).
- Packaging: QFN with exposed pad; “BGQW” denotes the specific package/leadframe/temperature grade.
- Typical use: generate stable low-voltage rails (Vcore, memory, etc.) with high efficiency.
For exact specifications (input range, output voltage options, current capability, switching frequency, pinout, and protection details), consult the RT9519BGQW datasheet from RichTek.

Package

RT9519BGQW is in a 16-pin QFN package, typically 4×4 mm (lead-free).

Pinout

- Pin count: 12 pins (QFN-12 package, 3x3 mm).
- Function: Dual synchronous DC-DC buck regulator (two-channel step-down converter) with integrated MOSFETs, used to generate two regulated rails from a higher input; includes typical control pins (EN, FB/SS, etc.).

Manufacturer

- Manufacturer: Richtek Technology Corporation (Richtek)
- Company type: Taiwan-based fabless semiconductor company that designs and sells power-management ICs, such as DC-DC converters, PMICs, and LED drivers, for consumer electronics and related applications.

Application

RT9519BGQW is a Richtek power-management IC for DC-DC conversion (buck regulator/controller). Typical applications include notebook/mobility devices and motherboard voltage rails, LCD backlight drivers, LED lighting gear, telecom/industrial power supplies, and other battery-powered consumer electronics requiring efficient voltage regulation.
