ROHM Product Detail

BD35395FJ-M
面向DDR-SDRAM的终端用线性电源

BD35395FJ-M是适用于JEDEC标准DDR1/2/3/3L-SDRAM的终端稳压器。内置N-MOSFET，漏型/源型最大可提供1A电流的线性电源。内部的OP-AMP采用高速设计，实现了优异的瞬态响应特性。为驱动内部的N-MOSFET，需要3.3V或5.0V偏压电源。为确保JEDEC规定的电压精度，本产品拥有独立的基准输入引脚（VDDQ）和独立的反馈引脚（VTTS），实现了优异的输出电压精度和负载调整率。

Reference Design / Application Evaluation Kit

 
    • Reference Design - REFPTR001
    • Power Management Reference design for Xilinx FPGA Spartan-7 platform

    • ROHM, together with Avnet, a leading supplier of electronic products and embedded solutions, developed a reference power supply optimized for Xilinx’s FPGA Spartan-7. In recent years, FPGA power supplies are increasingly demanding high accuracy low voltage, complicated startup sequences. At the same time, designers are constantly faced with the need to upgrade their designs to feature smaller form factors, greater energy savings, and lower costs, which are difficult to achieve within a short period. In response, ROHM offers an optimized power supply reference design for FPGA power supplies that allows designers to reduce development load while meeting market demands. The Spartan-7 (which this reference design was developed for) is ideal for industrial and consumer applications that leverage connectivity with sensor fusion and embedded vision. ROHM’s reference power supply design consists of a verified power supply that safely starts and operates Xilinx’s Spartan-7. This reference power supply includes the BD95602MUV power supply IC that delivers superior response characteristics, along with the BD9B305QUZ, BD9F500QUZ, and BD9F800MUZ designed to provide the current capability demanded for each power supply as well as the BD35395EFJ-M DDR3L termination power supply, making it possible to generate supply voltages that meet FPGA voltage accuracy specifications from 12V input while also supporting the necessary startup sequence. Reference design materials including circuit diagrams, BOMs, and board layouts are available for download.
