LM2596S-ADJ 为降压型(Buck)开关稳压器,工作电压范围宽(4.5V ~ 40V),输出电压可调(1.23V ~ 38.5V),最大输出电流可达3A。器件采用内置开关管、非同步整流拓扑,典型开关频率在127kHz ~ 173kHz,静态电流(Iq)约100µA,工作温度范围为-40℃ ~ +125℃。本型号以小封装(SOD-323)提供,适合空间受限、输入电压较高且对待机功耗有要求的中低功率降压场景。
为获得良好效率与稳定性,推荐注意以下几点:
SOD-323 为小型封装,导热受限,高输出电流时需严密关注结到环境的热阻:
总结:LM2596S-ADJ(TECH PUBLIC 封装 SOD-323)以其宽输入、电压可调和较低静态电流特点适合多种降压场合,但在高功率输出时需特别关注封装散热与外部整流器件的选择与布局。

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.
