GR6202是国睿(GR)推出的单通道同步降压DC-DC转换器,专为低电压、小电流需求的便携式电子设备设计,核心价值聚焦于「小体积、高效率、简化外围」——适配纽扣电池、单节锂电池低压段等主流供电场景,满足智能穿戴、传感器节点等紧凑空间内的供电需求,是低功耗设备的高性价比稳压方案。
支持1.8V~3.2V DC输入,覆盖三类主流低功耗供电场景:
采用900kHz固定开关频率,优势显著:
采用同步降压拓扑+内置高/低侧MOSFET,无需外置功率管,减少3~5个外围元件,PCB布局更紧凑;同步整流替代续流二极管,轻载效率可达85%以上(典型值),延长电池续航。
相比异步Buck(仅内置高侧开关),同步拓扑通过内置低侧MOSFET降低导通损耗60%以上,尤其在输出电流100~200mA区间效率提升明显,适合电池供电设备的低功耗需求。
集成行业标准保护机制,提升可靠性:
采用SOT-23-5封装(尺寸1.6mm×2.9mm×1.1mm),是小型化设备的理想选择,适配智能手环、蓝牙耳机、电子标签等紧凑PCB空间,单颗芯片占用面积不足5mm²。
工作温度覆盖**-30℃~+55℃**,满足日常使用环境:
GR6202的参数特性使其适配多类低功耗设备:
GR6202以「宽输入、高频、小封装、内置开关管」为核心竞争力,精准匹配便携式低功耗设备的供电需求——简化设计的同时提升效率与可靠性,是智能穿戴、传感器节点等领域的高性价比选择,可有效降低终端产品的体积与成本。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
