Descripción general

Description

RT9119GQV is RichTek’s synchronous buck (step-down) DC-DC regulator in a compact QFN package. It integrates high-side and low-side MOSFETs for efficient power conversion, allowing a higher input voltage to be stepped down to a stable, lower output rail used by digital and analogue circuits. The device typically offers adjustable output via an external resistor feedback network, plus features such as enable/shutdown, soft-start, overcurrent protection, undervoltage lockout, and thermal protection. The GQV suffix identifies the specific package variant (a RoHS-compliant, small QFN form factor). Applications include CPU core and memory rails, other onboard DC-DC conversion tasks in embedded systems, consumer electronics, and any space-constrained power supply needing high efficiency and fast transient response. For exact electrical specs (input range, output voltage options, switching frequency, and current capability), refer to the official datasheet.

Package

QFN-16 package, 3×3 mm (Richtek RT9119GQV).

Pinout

Pin count: 8 pins (8-pin package).
Function: A high-efficiency buck (step-down) DC-DC regulator used to convert a higher input voltage to a regulated lower output.

Manufacturer

- Manufacturer: Richtek Technology Corporation (Richtek).
- What kind of company: A Taiwan-based semiconductor company that designs and sells analog and mixed‑signal power‑management ICs (e.g., DC-DC converters, regulators). It is a fabless IC design house that outsources fabrication.

Application

RT9119GQV is a high-efficiency buck regulator. Typical application areas include:
- Portable and battery-powered devices
- Power management for smartphones, tablets, and wearables
- Core rails for SoCs, FPGAs, and ASICs
- USB-C/USB PD charging and power-delivery circuits
- IoT sensors, microcontroller platforms, and embedded systems
- Consumer electronics such as set-top boxes, cameras, and peripherals

Equivalent

RT9119GQV is a Richtek buck regulator. Equivalents depend on its exact specs. Please share: Vin range, Vout, Iout, switching frequency, and package/pinout. With those, I can give proper cross-references (or point you to Richtek’s cross-reference tool). Without specs, any equivalent list would be unreliable.
