LM2596HVS-5.0/TR是华冠半导体(HGSEMI)推出的高压异步降压开关稳压器,专为工业级、车载等恶劣环境下的高压输入降压场景设计。其核心价值在于兼顾宽输入电压范围、高输出电流能力、工业级宽温特性,同时内置高压开关管简化外围电路,无需外置功率管即可实现3A持续输出,是替代传统线性稳压器(如78xx系列)的高效方案。
该产品的核心参数针对高压应用优化,具体如下:
LM2596HVS-5.0/TR采用TO-263-5贴片封装(尺寸紧凑,适合高密度PCB布局),引脚定义清晰易识别:
引脚编号 引脚名称 功能说明 1 Vin 输入电压端(需并联高压滤波电容抑制尖峰) 2 GND 电源地(需与输入/输出地共地,减少压降) 3 FB 反馈端(固定5V型号内部已连接至1.2V基准,无需外部电阻) 4 SW 开关节点(接电感、续流二极管阳极) 5 Vout 输出电压端(接输出滤波电容稳定纹波)凭借高压宽温特性,该产品广泛应用于以下领域:
为保证稳定工作,需注意以下设计要点:
LM2596HVS-5.0/TR是一款高性价比高压降压稳压器,核心优势在于:
其紧凑的TO-263-5封装与成熟的应用方案,使其成为工业、车载等高压场景下的理想选择,可有效降低系统功耗与发热,提升设备稳定性。

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.
