BD35395FJ-M
針對DDR-SDRAM的終端用線性電源

BD35395FJ-M是適用於JEDEC標準DDR1/2/3/3L-SDRAM的終端穩壓器。內建N-MOSFET，漏極/源極最大可提供1A電流的線性電源。內部的OP-AMP採用高速設計，實現了優異的暫態響應特性。為驅動內部的N-MOSFET，需要3.3V或5.0V偏壓電源。為確保JEDEC規定的電壓精度，本產品擁有獨立的基準輸入引腳（VDDQ）和獨立的反饋引腳（VTTS），實現了優異的輸出電壓精度和負載調整率。

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.
