BD35395FJ-M
DDR-SDRAM 터미네이션용 리니어 전원
BD35395FJ-M
DDR-SDRAM 터미네이션용 리니어 전원
BD35395FJ-M은 JEDEC 준거 DDR1 / 2 / 3 / 3L-SDRAM에 대응하는 터미네이션 레귤레이터입니다. N-MOSFET를 내장하여 싱크 / 소스로 최대 1A까지 공급 가능한 리니어 전원입니다. 내부의 OP Amp를 고속 설계함으로써 우수한 과도 응답 특성을 실현합니다. 내부의 N-MOSFET를 구동하기 위해 바이어스용 전원으로 3.3V 또는 5.0V가 필요합니다. JEDEC로 규정된 전압 정밀도를 유지하기 위해 독립된 기준 입력 Pin (VDDQ)와 독립된 피드백 Pin (VTTS)를 구비하여, 우수한 출력전압 정밀도 및 로드 레귤레이션을 실현합니다.

- 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.
