Overview

Description

RT9187GSP is a RichTek DC-DC buck regulator IC (part of the RT9187 family) used for efficient step-down Power Conversion in portable electronics. It typically integrates the switching MOSFET and control logic in a compact GSP package for minimal external parts. Key features usually include adjustable output via resistor feedback, high efficiency across load ranges, enable/soft-start control, and protective functions such as over-current, thermal shutdown, and undervoltage lockout. It’s suitable for powering cores or I/O rails in smartphones, tablets, wearables, cameras, and other battery-powered devices. Note that exact specifications (input range, output voltage, switching frequency, package) vary by revision; consult the latest RT9187GSP datasheet and application notes for precise design details. If you’d like, I can summarize the current datasheet or provide a typical application circuit.

Package

The RT9187GSP uses an 8‑pin SOP package (SOP‑8). The “GSP” suffix denotes Richtek’s Green/SOP package variant.

Pinout

- Pin count: 8 pins (GSP package).
- Function: Synchronous buck DC-DC converter regulator (step-down), with integrated high‑ and low‑side MOSFETs to convert a higher input voltage to a controlled lower output.

Manufacturer

- Manufacturer: Richtek Technology Corporation (Richtek).
- What kind of company: A Taiwanese semiconductor company that designs and manufactures analog and mixed-signal power-management ICs (PMICs), including DC-DC converters, LED drivers, battery charging ICs, for consumer, automotive, and industrial applications.

Application

RT9187GSP is a high‑efficiency DC‑DC buck regulator for system power in compact and portable electronics. Typical applications:
- SoC/CPU core and memory rails in smartphones, tablets, ultrabooks
- VRMs for embedded microcontrollers and GPUs
- Power management in IoT devices, wearables
- Set‑top boxes, TVs, and home networking equipment
A compact, efficient solution for various consumer and embedded electronics requiring DC‑DC regulation.
