产品详情

ADP2386是一款同步降压DC-DC稳压器,集成了一个44 mΩ高端功率MOSFET和一个11 mΩ同步整流器MOSFET并采用紧凑型4 mm × 4 mm LFCSP封装,可提供高效解决方案。该器件使用峰值电流模式、恒频脉冲宽度调制(PWM)控制方案,具备出色的稳定性和瞬态响应。ADP2386的开关频率可在200 kHz至1.4 MHz范围内进行编程。为了将系统噪声降至最低,同步功能允许开关频率与外部时钟同步。

ADP2386只需极少的外部元件,输入电压范围为4.5 V至20 V。输出电压可在0.6 V至输入电压的90%范围内进行调整,提供高达6 A的连续电流。各IC在禁用时从输入源汲取的电流不到110 μA。

该稳压器针对需要高效率和设计灵活性的高性能应用。外部补偿和可调软启动功能提供设计灵活性。电源良好输出和精密使能输入提供简单可靠的电源时序。

其它重要特性包括欠压闭锁(UVLO)、过压保护(OVP)、过流保护(OCP)、短路保护(SCP)和热关断(TSD)。

ADP2386在-40°C至+125°C的结温范围内工作,采用24引脚4 mm × 4 mm LFCSP封装。

产品详情

The ADP2384/ADP2386 evaluation board is a complete, 4 A/6 A, 20 V, step-down regulator solution that allows users to evaluate the performance of the ADP2384/ADP2386 with a near ideal printed circuit board (PCB) layout.

The switching frequency can be programmed between 200 kHz and 1.4 MHz, or it can be synchronized to an external clock with a 180° phase shift, which provides the possibility for a stackable multiphase power solution.


The output of the ADP2384/ADP2386 evaluation board is preset to 3.3 V and the switching frequency is set to 600 kHz. Different output voltage settings can be achieved by changing appropriate passive components. The ambient temperature operating range is −40°C to +85°C.


Full details on the ADP2384 and ADP2386 regulators are provided in the ADP2384 and ADP2386 data sheets, available from Analog Devices, Inc., which should be consulted in conjunction with this user guide.

产品详情

In order to get the correct unpopulated evaluation board with an appropriate Bill of Materials and Schematic, you need to use the button for "Request Evaluation Board" from within the design tool. Make sure the design tool is in a state that matches your desired power requirements.

This will create a template email that will request from us the proper blank evaluation board for that ADI part and your application's power parameters.


Note: Some parts have multiple blank boards for high/low current or for different topologies (Boost, SEPIC, SEPIC-Cuk), while other blank boards support multiple ADI parts. This is why it is important to run the design tool with your parameters before making your email request from the tool.
