SGM66099-ADJYTDI6G/TR 产品概述

一、产品概述

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。

二、主要性能特点

  • 输入电压:0.9V ~ 5.2V;输出电压:2.5V ~ 5.2V(可调);输出电流:最大 300mA。
  • 工作频率:1.2MHz,利于减小外部元件体积。
  • 超低静态电流:典型 0.6µA(提高待机续航)。
  • 同步整流与输出断开功能:关断时最小化电池泄漏。
  • 轻载高效模式、逐波限流(cycle‑by‑cycle current limit)、短路保护与热关断。
  • 支持 down 模式(当输入高于输出仍能稳压),当输入比设定输出高出约 300mV 时进入透通模式以降低功耗。

三、电气指标与工作条件

  • 输入电压范围:0.9V ~ 5.2V
  • 输出电压范围:2.5V ~ 5.2V(ADJ 可调版本)
  • 开关频率:1.2MHz
  • 输出电流能力:300mA(在 3.3V→5V 转换条件下)
  • 静态电流:典型 0.6µA;工作温度:-40°C ~ +85°C
  • 封装:TDFN-2×2-6AL(ADJYTDI6G/TR);另有 Green WLCSP 可选

四、保护与工作模式说明

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。

五、典型应用与设计要点

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:

  • 使用低 DCR、高饱和电流的小型功率电感以匹配 1.2MHz 工作频率;
  • 输入/输出陶瓷旁路电容尽量靠近器件 VIN/GND 与 VOUT/GND 引脚,减小回流环路;
  • PCB 布局注意最短开关回路,露铜/散热垫利于热量扩散;
  • 若需最高效率,外部元件(电感、电容、肖特基/降压二极管无须)应根据应用电流与 EMI 需求优化。

六、封装与采购信息

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。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
