LM2596S-ADJ-MS 为降压型开关稳压器,内置开关管,单路输出、可调型设计。工作输入电压范围宽(4.5V~40V),输出电压可调(约1.2V~37V),最大输出电流3A,开关频率约150kHz。器件静态电流约5mA,工作温度范围-40℃至+125℃(TA),封装为TO-263-5L,品牌:MSKSEMI(美森科)。该器件不采用同步整流,需外接肖特基二极管进行整流与回流路径设计。
在高Vin与高Iout条件下,器件和周边器件会产生较大损耗。建议根据实际功率损耗评估散热需求:采用较大散热焊盘、热孔通到内层/背面铜,以及必要时加装散热片或风冷。工作环境高温时应适当降额使用以保证长期可靠性。
TO-263-5L 封装便于板上散热与高电流焊接。采购时确认MSKSEMI(美森科)版本的引脚定义与参考设计,与目标系统的输入范围和器件替代兼容性;同时为非同步整流版本,需同时备配合适的肖特基二极管和外部电感器件。
以上为LM2596S-ADJ-MS 的产品概述与设计参考,便于快速评估在具体电源方案中的可用性与注意事项。若需典型电路图、外围元件选型表或热阻计算示例,可提供具体工作点(Vin、Vout、Iout)以便精确计算与推荐。

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.
