Description

RT9173CGSP is a Richtek DC-DC buck regulator packaged in the CGSP form factor. It’s designed to convert a higher input voltage down to a stable, lower output rail for portable and embedded electronics.
Key points:
- Switching regulator with integrated control logic; output voltage is set via external feedback (fixed or adjustable versions).
- Includes enable/soft-start, overcurrent protection, UVLO/thermal protection.
- Requires external components: inductor, input/output capacitors; may use a catch diode if operated in asynchronous mode (or a synchronous design if supported).
- Typical applications: power rails for microcontrollers, processors, memory, sensors in mobile/embedded devices.
- For exact specs (input range, output options, current capability, pinout), consult the RT9173 datasheet and the CGSP packaging details.

Features

RT9173CGSP is a single-channel buck regulator. Key features typically include:
- Wide input voltage range and high efficiency for portable applications
- Integrated power MOSFETs with current‑mode control
- Fixed-frequency operation with soft-start
- Output: fixed or adjustable via external feedback
- Enable/shutdown control
- Protections: over-current/short-circuit, over-temperature, UVLO
- Low quiescent current (suitable for battery-powered devices)
- Suitable for compact designs with a small CGSP package
Note: exact specs (input range, available output voltages, switching frequency, and current capability) vary by variant. Refer to the official datasheet for precise figures and pinout.

Pinout

8 pins. It is a buck (step-down) switching DC-DC regulator (high-efficiency regulator) with an enable input.

Manufacturer

- Manufacturer: Richtek Technology Corporation (Richtek).
- What kind of company: A Taiwanese fabless semiconductor company that designs power-management ICs (DC-DC regulators, LDOs, PMICs, etc.).

Application

RT9173CGSP is a compact, high-efficiency DC-DC buck regulator used to generate stable supply rails in space‑constrained electronics. Typical application areas include:
- Smartphones, tablets, wearables (battery-powered devices)
- Laptops/notebooks and ultrabooks (core voltage rails)
- Embedded systems, microcontrollers, FPGAs/ASICs
- Monitors, LCD TVs, set‑top boxes, and consumer video equipment
- USB power management and charging circuits
- Networking equipment (routers, modems) and other small form‑factor electronics
Note: package variant CGSP suits compact boards with low EMI and minimal PCB footprint.

Package

RT9173CGSP is in a 6-pin SC-70 (SOT-23-6) package.
