L7987LTR 产品概述
概述
L7987LTR 是意法半导体（STMicroelectronics）推出的一款高性能的降压DC-DC电源芯片，专为满足高效率、宽输入电压范围需求的应用而设计。该元件具有可调输出功能，适合多种电子设备，能够在广泛的输入电压（4.5V 至 61V）下稳定地提供调节后的电压（输出范围从 0.8V 到 61V，最大输出电流为 2A）。L7987LTR 采用HTSSOP-16封装，设计为表面贴装型，有助于提高集成度并节省空间。
功能与应用
L7987LTR 的主要功能是将较高的输入电压有效地降到所需的低输出电压，这对于需要较高输入电压源的系统（例如汽车电子、工业控制、通信设备等）尤为重要。其广泛的输入电压范围使其能够适应多种电源环境下的工作需求。可调输出特性为电路设计提供了更大的灵活性，使工程师可以根据具体应用的要求进行调整。
由于其支持的工作温度范围从 -40°C 到 150°C，L7987LTR 同时适用于高温和恶劣环境下的应用。这使其在汽车电子、航空航天设备及工业设备等领域的应用更为可靠。
设计特性
L7987LTR 拥有多种优良的设计特性：
高效率：L7987LTR 设计上专注于提供较低的功率损耗，确保在不同负载条件下运作时都能维持高效率，减少发热量，提高整体系统的稳定性。
可调输出：与固定输出的DC-DC芯片相比，该款元件允许用户根据需求调整输出电压，以满足不同电化学负载的需求。
频率范围：L7987LTR 的开关频率范围为 250kHz 到 1.5MHz，用户可以根据应用要求灵活选择开关频率，以优化电路性能。
耐受电压：支持高达 61V 的输入电压，L7987LTR 可应用于高压电源系统，而其输出电压最低可调至 0.8V，非常适合低电压负载的供电需求。
散热解决：HTSSOP-16封装特别设计用于提高热性能，确保芯片在长时间工作时仍能保持稳定的输出状态，而不会因过热而造成故障。
非同步整流：该芯片设计成无同步整流器，虽然这可能在部分应用中影响效率，但其简化的设计也减低了外围组件的复杂性，使得电路设计更加简洁。
结论
L7987LTR 是一款功能强大且适用性广泛的降压DC-DC电源芯片，其出色的性能指标、宽输入范围以及灵活的输出调节选项使得它在现代电子应用中显得尤为重要。无论是在汽车电子、工业控制还是通信设备等领域，其表现都能够满足客户的需求，并带来出色的性能。此外，意法半导体卓越的技术和可靠的产品质量也为用户提供了安心保障，促进了其在市场上的广泛应用。选择 L7987LTR，将为您的设计带来可靠的电源解决方案。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
