产品详情

LTC^®4357 是一款正高电压理想二极管控制器，用于驱动一个外部 N 沟道 MOSFET 以取代一个肖特基二极管。当在二极管“或”和高电流二极管应用中使用时，LTC4357 能够降低功耗、热耗散、电压损失并缩减 PC 板面积。

LTC4357 能够很容易地对电源进行“或”操作，以提高总体系统可靠性。在二极管“或”应用中，LTC4357 用于控制 MOSFET 两端的正向电压降，以确保从一条路径至另一条路径的平滑电流转移而没有振荡现象。在电源发生故障或短路的情况下，快速关断操作可最大限度地减小反向电流瞬变。

优势和特点

Analog Devices has worked closely with Intel PSG to develop verified power solutions that optimize cost, size and efficiency in high performance applications.
The validated power solutions include uModules power products that address time and space constraints while delivering high efficiency, reliability, and low noise.
The actual power tree represents the best solution at time of design.
A recommended power tree has also been included to present the ideal solution at time of Stratix 10 GX PCIe development kit release. An updated alternate version of the power tree represents the latest solutions available from Analog Devices. For many applications, an intermediate rail is not ideal, so recommendations an alternate power tree that allow for direct power conversion from 12V input is provided below.
