TMI3255T 是一款降压型开关稳压器,工作电压范围为 4.5V18V,最大输出电流 5A,开关频率 600kHz,采用降压拓扑并内置开关管,输出可调,工作结温范围 -40℃+125℃。器件采用 SOT-23-6 小封装,静态电流仅 340µA,适合对尺寸和功耗有严格要求的点电源应用。
TMI3255T 集成常用电源保护功能以提升系统可靠性,包括欠压锁定(UVLO)、过流/短路保护(OCP/SC)、热关断(TSD)以及软启动机制,减小开机冲击并具备良好瞬态响应能力(具体保护门限请参考数据手册)。
SOT-23-6 封装体积小但对散热敏感。建议在 PCB 下方及周围扩展铜面积以提高导热,并在高功率工作条件下注意输出电流的热降额。长时间 5A 输出需评估实际温升并做好散热设计。
TMI3255T 提供了在宽输入、较高电流下的小封装、低静态电流降压解决方案。600kHz 的工作频率有助于减小外部被动元件体积,340µA 的静态电流利于待机节能,SOT-23-6 封装便于体积受限的产品实现高密度电源布局。结合合理的 PCB 布局与散热设计,TMI3255T 可在汽车、工业与消费类电子等多类场合作为可靠的点电源方案。若需详细电性能曲线与典型应用电路参数,请参考厂家数据手册或样片评估。

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.
