XL9028(品牌:XLSEMI / 芯龙)是一款同步整流降压型开关稳压器,集成高侧/低侧开关管,单通道输出,适用于5V45V宽输入电压的电源设计。输出可调范围1.25V40V,最大输出电流6A,开关频率中心值约120kHz(96kHz144kHz 可变),静态工作电流仅2.3mA。器件以TO-263-7L封装提供,工作温度覆盖-40℃+125℃,并内置过流保护,适合工业、通信、电源模块等对体积与效率有要求的场景。
在高输入差与大输出电流情况下,器件功耗上升,需评估结温并做好散热设计。推荐在PCB下方和周围增加铜面积、布置热孔通至另一层,并预留足够的散热裕量;实际应用中请根据环境温度与负载工况进行热仿真或实测。
XL9028 提供了低静态电流、宽输入电压与高输出电流的平衡方案,但具体的保护行为、开机顺序、软启动及环路补偿细节请以厂商数据手册为准。在设计阶段应验证稳定性、瞬态响应与效率曲线,并根据PCB工艺调整布局与滤波元件。如需样片、评估板或完整数据手册,请联系 XLSEMI(芯龙)或其授权分销渠道获取最新资料。

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.
