TPS561246DRLR是德州仪器(TI)推出的1A输出同步降压转换器,采用降压式拓扑结构,专为需要小封装、高效率、宽输入电压范围的电源设计场景打造。该器件内置同步整流开关管,支持强制连续导通模式(FCCM),可实现低输出纹波与稳定的负载响应,适用于多种工业、消费及汽车电子应用。
采用SOT-5X3(DRL)封装,6引脚设计,尺寸紧凑(1.6mm×1.6mm×0.8mm),可显著节省PCB布局空间,适合高密度电源模块或小型化终端产品(如便携式设备、物联网节点)。封装引脚功能清晰,简化焊接与调试流程。
-40℃至+125℃的结温范围,使其可在极端环境下稳定工作,如工业控制单元、车载辅助传感器、户外通信设备等。
FCCM模式下轻载纹波低,配合内置软启动功能,可减少上电冲击,适合对电源噪声敏感的应用(如模拟信号采集、低功耗MCU供电)。
同步整流与高频设计结合,在全负载范围内保持较高效率(满载效率超92%),延长电池供电设备的续航时间(如手持终端、可穿戴设备)。
该器件凭借紧凑封装、宽温特性与灵活设计,成为中小功率电源设计的优选方案,覆盖多领域终端产品的供电需求。

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.
