Descripción general

Description

RT9173CGSP is a RichTek DC-DC buck (step-down) switching regulator in a compact CGSP package. It’s used to convert a higher input voltage (typical battery/USB rails) to a stable lower supply for digital and analog circuits. The device is designed for portable electronics and compact systems, offering features common to RT917x family such as enable/shutdown control, soft-start, protection against overcurrent/short circuits, and thermal shutdown, with options for adjustable or fixed output voltages. It aims for high efficiency and good load transients, suitable for battery-powered devices, cameras, and MCU-based boards. For exact electrical specs (input range, available output voltages, current capability, switching frequency, and pinout), consult the RT9173CGSP datasheet and product page.

Features

- High-efficiency synchronous buck DC-DC converter (integrated high- and low-side MOSFETs).
- Input voltage range suitable for battery/USB apps (typical 2.5–5.5 V region).
- Adjustable output via external feedback resistors (output voltage programmable).
- Enable pin to turn device on/off.
- Soft-start to limit inrush and improve transient response.
- Auto mode for light-load efficiency (PWM/PFM or similar).
- Protections: undervoltage lockout, overcurrent/short-circuit current limit, thermal shutdown.
- Low quiescent current for better battery life.
- Small CGSP package (8-pin) suitable for compact designs.
Note: exact input range, output voltage range, switching frequency, and current capability vary by revision; please consult the RT9173CGSP datasheet for precise specifications.

Package

The RT9173CGSP is supplied in a 5‑pin SOT‑23 package (SOT‑23‑5 / SC‑70‑5 form factor).

Pinout

The RT9173CGSP is supplied in a 5‑pin SOT‑23 style package (5 pins). It is a low‑dropout (LDO) linear voltage regulator. Typical pin functions are:
- VIN: regulator input
- EN (or SHDN): enable/shutdown control
- GND: ground
- VOUT: regulated output
- FB/ADJ: feedback/adjust pin for the fixed or adjustable output version
(Exact pin numbering and whether the part is fixed‑output or adjustable depend on the specific RT9173 variant—please confirm with the official datasheet for pin‑out and electrical details.)

Manufacturer

Manufacturer: Richtek Technology Corporation (Richtek).
What kind of company: Richtek is a Taiwan‑based fabless semiconductor company that designs and supplies power‑management integrated circuits (LDOs, DC‑DC converters, PMICs) for consumer, industrial, and computing applications.

Application

RT9173CGSP is a voltage regulator IC (LDO) used to supply stable rails in portable and battery-powered devices. Typical applications include powering microcontrollers, memory, sensors, and peripherals in smartphones, wearables, IoT devices, cameras, USB devices, and other embedded systems needing compact, low-quiescent-power regulation.
