H8116A30NR是上海矽朋(Siproin)推出的一款升压型固定输出DC-DC电源芯片,专为低功耗、小体积电池供电场景设计,集成同步整流与内置开关管,兼顾效率与便携性,适用于宽温环境下的各类便携及IoT设备。
H8116A30NR聚焦电池供电设备的低功耗+小体积需求,核心设计亮点包括:
支持单节锂电池放电截止状态(2.1V)仍稳定工作,同时覆盖2节AA/AAA干电池(3.0V)、USB 5V(宽范围兼容),无需额外升压/降压转换,简化系统设计。
待机模式下仅消耗15μA电流,是同类异步整流芯片的1/3~1/5,适合长期低功耗待机的IoT节点、智能手环等设备。
采用固定300kHz频率,平衡效率与元件体积:电感可选用10μH小封装(如SOT-23),电容用1μF~10μF陶瓷电容,无需 bulky 元件,适配便携设备高密度布局。
内置NMOS下管替代续流二极管,导通压降从0.3~0.7V降至0.1V以下:
H8116A30NR采用升压(Boost)拓扑,核心工作流程:
同步整流的核心优势是降低导通损耗,尤其在低电流场景下,避免续流二极管的压降浪费,提升电池续航。
SOT-23(5引脚)封装,尺寸仅2.9mm×2.5mm×1.1mm,适合便携设备的小面积PCB设计,可兼容自动贴装工艺。
H8116A30NR凭借宽输入、低功耗、高效率、小体积四大核心优势,成为电池供电便携设备、低功耗IoT设备的理想升压电源方案,尤其适合对待机时间、体积有严格要求的场景。

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.
