产品详情

LTM^®4633 μModule^® (微型模块) 稳压器将三个完整的 10A 开关模式 DC/DC 转换器整合在一个小型封装之中。封装中内置了开关控制器、功率 FET、电感器和大多数支持组件。LTM4633 的三个稳压器依靠 4.7V 至 16V 输入电压轨或 2.375V 至 16V (采用一个外部 5V 偏置) 电压运作。V_OUT1 和 V_OUT2 输出范围为 0.8V 至 1.8V，而 V_OUT3 输出范围则为 0.8V 至 5.5V。每个输出由一个外部电阻器来设定。

高开关频率和一种电流模式架构的运用实现了针对电压和负载变化的快速瞬态响应，并且未牺牲稳定性。该器件支持频率同步、V_OUT1 和 V_OUT2 的多相并行运作、软起动以及用于电源轨排序的输出电压跟踪。

故障保护功能包括过压、过流保护和温度监视。该电源模块采用节省空间的耐热性能增强型 15mm x 15mm x 5.01mm BGA 封装。LTM4633 符合 RoHS 标准，并采用无铅涂层。

QUAD-MxFE Platform

16Tx/16Rx Direct L/S/C-Band Sampled Phased-Array/RADAR/EW/SATCOM Development Platform

DC1905A

LTM4633 Demo Board | Triple Buck µModule Regulator, 4.7V ≤ V_IN ≤ 16V, V_OUT1 & V_OUT2 = 0.8V to 1.8V @ 10A, V_OUT3 = 0.8V to 5.5V @ 10A

QUAD-MxFE Platform

查看此评估套件详细信息

The Quad-MxFE System Development Platform contains four MxFE® software defined, direct RF sampling transceivers, as well as associated RF front-ends, clocking, and power circuitry. The target application is phased array radars, electronic warfare, and ground-based SATCOM, specifically a 16 transmit/16 receive channel direct sampling phased array at L/S/C band (0.1 GHz to ~5GHz). The Rx & Tx RF front-end has drop-in configurations that allow for customized frequency ranges, depending on the user’s application.

The Quad-MxFE System Development Platform highlights a complete system solution. It is intended as a testbed for demonstrating multi-chip synchronization as well as the implementation of system level calibrations, beamforming algorithms, and other signal processing algorithms. The system is designed to mate with a VCU118 Evaluation Board from Xilinx®, which features the Virtex® UltraScale+™ XCVU9P FPGA, with provided reference software, HDL code, and MATLAB system-level interfacing.

In addition to the Quad-MxFE Digitizing Card, the kit also contains a 16Tx / 16Rx Calibration Board that is used to develop system-level calibration algorithms, or otherwise more easily demonstrate power-up phase determinism in situations pertinent to their own use case. The Calibration Board also allows the user to demonstrate combined-channel dynamic range, spurious, and phase noise improvements and can also be controlled via a free MATLAB add-on when connected to the PMOD interface of the VCU118.

The system can be used to enable quick time-to-market development programs for applications like:

ADEF (Phased-Array, RADAR, EW, SATCOM)
Communications Infrastructure (Multiband 5G and mmWave 5G)
Electronic Test and Measurement

DC1905A

查看此评估套件详细信息

Demonstration circuit DC1905A features the LTM4633EY, a high efficiency, triple 10A step-down power μModule^® regulator. The input voltage range is from 4.7V to 16V with common input source, or 2.375V to 16V with an external bias supply. The output voltage range is 0.8V to 1.8V for Channel 1 and Channel 2, 0.8V to 5.5V for Channel 3. Derating is necessary for certain V_IN, V_OUT, frequency and thermal conditions. The DC1905A offers access to the TRACK/SS pins allowing the user to program output tracking or soft-start period. The board operates in continuous conduction mode in heavy load conditions. For high efficiency at low load currents, the MODE jumper (JP4) selects pulse-skipping mode for noise sensitive applications or Burst-Mode^® operation in less noise sensitive applications. Channel 1 and 2 can be connected in parallel for a single 20A output solution with optional jumper resistors.
