VIPERGAN50TR是意法半导体(ST) 推出的集成式隔离AC-DC控制器+稳压器,专为中小功率(50W) 电源设计,兼具高效能、高可靠性与小型化特点,可满足消费电子、工业、车载等多领域的电源需求。作为隔离型方案,它无需额外隔离器件,简化了电源系统架构。
反激拓扑是隔离电源的成熟方案,具备宽输入电压范围(适配市电波动)、简单变压器设计(无需复杂绕组)等优势,适合中小功率隔离电源。
VIPERGAN50TR采用谷值开关(Valley Switching) 的QR模式:开关管关断后,变压器漏感与输出电容发生谐振,开关管在电压谷值时导通——这一设计可大幅降低开关损耗,提升转换效率(可达85%以上),同时减少EMI电磁干扰,降低外围滤波成本。
产品内置3项核心保护功能,从硬件层面提升系统稳定性:
这些保护无需额外外围电路,简化设计的同时,降低了系统故障风险。
采用QFN-15(5×6mm) 表面贴装封装,体积紧凑,适合高密度PCB设计(如笔记本适配器、机顶盒电源模块),可有效节省产品内部空间。
VIPERGAN50TR通过集成度、效率与可靠性的平衡,成为中小功率隔离电源的高性价比选择,可快速适配不同行业的电源设计需求。

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.
