概要

Description

RT9068GSP is a Richtek high-efficiency synchronous buck DC-DC converter in the RT9068 family. It’s a compact power-management IC that converts a higher input voltage (VIN) to a lower, stable output voltage (VOUT) for microprocessors, memory, and other peripherals. The device typically integrates the switching MOSFETs and control logic, offering features such as enable/shutdown, soft-start, over-current/short-circuit protection, over-temperature protection, and sometimes remote-sense or UVLO, depending on the variant. The “GSP” suffix denotes a specific packaging option for the component.
The RT9068GSP family provides different current ratings and switching frequencies to fit various designs. For exact electrical specifications (VIN range, VOUT options, max current, efficiency, pinout, protections), consult the official RT9068GSP datasheet and supplier product pages.

Features

RT9068GSP features (highlights):
- High-efficiency step-down (buck) regulator with integrated MOSFETs (synchronous topology).
- Wide input voltage range suitable for battery, automotive and general DC sources.
- Adjustable output via external feedback network (fixed versions available).
- MHz-range switching frequency enables small external inductor and capacitor sizes.
- Enable/shutdown control for hardware power-down.
- Soft-start and programmable rise time for controlled startup.
- Low quiescent current with good light-load efficiency (dynamic mode options).
- Robust protections: undervoltage lockout, overcurrent/short-circuit protection, over-temperature shutdown, and output overvoltage protection.
- Fast transient response and stable regulation under varying loads.
- Small package option (GSP) suitable for compact designs; RoHS-compliant.
Note: exact electrical specs (input range, output range, current capability, switching frequency) vary by revision; please consult the official datasheet for precise numbers.

Package

RT9068GSP is in an 8-pin QFN package (3×3 mm) with an exposed pad (EP).

Pinout

Pin count: 8 pins (GSP package).
Function: RT9068GSP is a single-channel DC-DC buck (step-down) regulator with an enable input and feedback for adjustable output. It converts a higher Vin to a lower Vout to generate regulated rails for other circuitry.

Manufacturer

- Manufacturer: Richtek Technology Corporation (Richtek)
- Company type: A Taiwan-based fabless semiconductor company that designs and markets analog and mixed-signal ICs, especially power management ICs (PMICs) for consumer electronics.

Application

Applications of RT9068GSP:
- Portable, battery-powered devices (mobile phones, tablets, wearables, GPS, cameras)
- IoT and smart-home products (sensors, gateways)
