BD9B305QUZ
2.7V to 5.5V Input, 3.0A Integrated MOSFET Single Synchronous Buck DC/DC Converter
BD9B305QUZ
2.7V to 5.5V Input, 3.0A Integrated MOSFET Single Synchronous Buck DC/DC Converter
BD9B305QUZ is a synchronous buck DC/DC converter with built-in low on-resistance power MOSFETs. It is capable of providing current up to 3A. It features fast transient response due to constant on-time control system. The Light Load Mode control improves efficiency in light-load conditions. It is ideal for reducing standby power consumption of equipment. Power Good function makes it possible for system to control sequence. It achieves the high power density and offer a small footprint on the PCB by employing small package.

- 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.
