SSP9492是一款降压型(BUCK)直流-直流转换器,采用经典降压拓扑实现高压输入到低压/中压输出的高效转换。产品内置功率开关管,无需外置MOSFET即可完成功率变换,既简化电路设计,又降低系统BOM成本与PCB空间占用。该拓扑结构天然适配宽电压范围转换,工作稳定性强,适合多种功率级别的供电需求。
SSP9492的输入电压范围覆盖9V~90V,可兼容工业直流母线(48V、60V、90V)、车载12V/24V/48V系统,以及高功率消费电子适配器输出。输出电压支持1.25V~50V连续可调:既能满足低功耗MCU(1.8V、3.3V)的核心供电,也能为功率器件(电机驱动、功率放大器)提供最高50V中压电源,覆盖从低到中功率的多样化场景。
产品静态电流(Iq)仅2mA,轻载或待机状态下仍保持低功耗,适合对待机敏感的设备(如车载休眠系统、工业传感器节点)。开关频率固定为125kHz(中低频段):既避免高频(>500kHz)带来的EMI干扰,降低电磁兼容性设计难度;又比低频(<50kHz)所需电感体积更小,助力系统小型化。
SSP9492的工作结温范围为-40℃~+85℃,满足工业级环境要求,可稳定工作于严寒户外、高温控制柜、车载发动机舱等恶劣场景。结温设计充分考虑功率损耗与散热,配合ESOP-8封装的热性能,有效避免过热失效,提升系统长期可靠性。
采用ESOP-8贴片封装(典型尺寸5.0mm×6.0mm),尺寸紧凑,适合自动化贴装,节省PCB空间,满足便携式仪表、车载控制器等小型化设备需求。内置功率开关管、补偿电路等关键模块,仅需少量外围元件(电感、电容、电阻)即可构成完整电路,进一步简化设计流程。
SSP9492的宽电压、高可靠性特性使其适用于多领域:
作为一款高性价比宽电压降压转换器,SSP9492凭借宽输入输出范围、低静态功耗、高可靠性与小型化封装,成为工业、车载、通信等领域电源设计的优选方案。

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.
