VIPERGAN65TR 产品概述
一 概述
VIPERGAN65TR 是意法半导体（ST）面向离线开关电源的高压功率转换器，封装为 GQFN (5×6)，集成高压功率晶体管，耐压达 650V。器件工作电压范围宽（85V～265V），支持准谐振（QR）工作模式与反激式拓扑，适合用于小功率适配器、LED 驱动、 standby 电源等离线电源方案。器件内置多种保护功能，适用于对可靠性和系统保护要求较高的应用场景。
二 主要特性
- 宽输入电压：85V ～ 265V，直接面对市电输入的设计需求。
- 开关频率范围：10kHz ～ 240kHz，可根据负载与 EMI 要求调节设计。
- 功率耗散（Pd）：65W（器件耗散能力），在热设计时需充分考虑。
- 集成高压晶体管：耐压 650V，适合离线高压启动与开关动作。
- 最大占空比：5%（依据给定参数），适用于特定工作点下的控制策略。
- 拓扑与反馈：反激式拓扑，采用副边反馈实现输出稳压。
- 工作模式：准谐振（QR），有利于降低开关损耗与 EMI。
- 封装：GQFN（5×6），有利于热传导与 PCB 布局紧凑。
三 保护与可靠性
器件集成了全面的保护功能：
- 欠压保护（UVP）与过压保护（OVP），保证系统在异常供电下的安全。
- 过流保护（OCP）与短路保护（SCP），有效限制输出异常电流对器件与负载的损伤。
- 过热保护（OTP），当结温过高时可靠地进入保护或关断状态。
这些保护特性对提高系统可靠性、满足安规与长期稳定性有重要作用。
四 应用场景
- 小功率离线适配器与充电器（如小型移动设备适配器、智能设备电源）。
- LED 驱动电源与照明控制器（中低功率场合）。
- 家电与工业控制的辅助电源与待机电源（STB、电表等）。
注：具体应用需结合输出隔离需求与安规设计，若需要隔离输出应在变压器及副边反馈设计上满足相关规范。
五 设计与布局要点
- 热管理：器件 Pd 为 65W，实际系统中需评估结到外界的热阻并设计合适散热路径（散热铜箔、热铜柱或散热片）。
- EMI 与滤波：QR 工作可降低开关应力，但仍需合理设计输入滤波与共模抑制，满足相关 EMI 标准。
- 控制与反馈：副边反馈方案需要可靠的光耦或辅助反馈电路，保证稳态与瞬态响应。
- 安规与隔离：若系统要求输出隔离，需按安规设计变压器及绕组间距；文档中给出的“非隔离”参数若与实际需求冲突，应以厂家资料为准。
六 总结
VIPERGAN65TR 以其高压耐受、准谐振控制与丰富的保护功能，适合用于多种离线低到中等功率电源设计。封装紧凑且适配常见反激拓扑，适合对尺寸与可靠性有要求的应用。在最终设计前，建议参考 ST 官方数据手册确认所有电气参数、引脚定义与热特性，并在 PCB 与外部元件选择上按安规与热设计原则展开验证。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
