LM2576HVS-12/TR 为一款降压(Buck)型开关稳压器,内置功率开关,适用于从高压直流输入降压到固定 12V 输出、最大输出电流 3A 的电源设计。该器件工作频率约 52kHz,静态工作电流仅 约 5mA,适合需要高效率与低静态损耗的工业与通信电源场合。器件支持宽输入电压(最高 60V),工作温度范围 -40°C 至 +125°C,单通道输出,封装为 TO-263-5(D2PAK)便于散热与 PCB 组装。品牌标示:HGSEMI(华冠)。
TO-263-5 封装具备较好的导热路径,建议在 PCB 设计时:
LM2576HVS-12/TR 提供了一种简洁、可靠的高压降压解决方案,适合需要从高电压源向 12V/3A 负载供电的场合。其内置开关与保护机制减少了外部元件的复杂性,TO-263-5 封装利于散热,但在实际设计中需重视版图布局、外部被动件的选型与热管理,以确保在各类工况下保持高效率与长期可靠性。

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.
