SGM66099 是一款超低静态电流的同步升压稳压器,工作电压范围 0.9V 至 5.2V,适用于单节锂电(Li‑Ion、Li‑Mn)、NiMH 等电池供电系统。器件内部集成开关管与高侧同步整流,典型静态电流仅 0.6µA,极大提升轻载工况下的能效和电池续航。器件可调输出 2.5V~5.2V,能在 3.3V→5V 转换时提供 300mA 输出,并在 200mA 负载时实现高达 93% 的转换效率。内部开关频率 1.2MHz,有利于采用小型电感与陶瓷电容,整体尺寸小。
SGM66099 集成多种保护机制:逐波限流保证短路或过载时限制开关电流,短路保护由同步整流配合实现以提高可靠性;过压保护和热关断防止器件及负载损伤。器件具备 down 模式,可在输入高于目标输出时继续稳压;当输入电压比输出设定值高出约 300mV 时,器件进入透通(pass‑through)模式以降低损耗并简化能量路径。关断时输出断开特性可避免电池向负载倒灌。
适用场景:可穿戴设备、便携式仪器、无线传感器节点、手持设备、低功耗物联网终端等电池供电系统。设计建议:
SGM66099 提供 TDFN‑2×2‑6AL 封装(ADJYTDI6G/TR 对应可调输出 TDFN 版本),同时有 Green WLCSP 方案以满足更小尺寸需求。器件符合无铅环保规范。具体订货、样片及参考设计请联系 SGMICRO(圣邦微)授权分销或当地技术支持获取详细资料与评估板。

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.
