The BD9F500QUZ from ROHM Semiconductor is a DC to DC Converter with Input Voltage 4.5 to 36 V, Output Voltage 1 0.6 to 14 V, Output Current 1 0 to 5000 mA, Storage Temperature -55 to 150 °C. Tags: Surface Mount, Buck/Step down. More details for BD9F500QUZ can be seen below.

ROHM Semiconductor BD9F500QUZ Nano Pulse Control™ Synchronous Buck DC-DC Converter features built-in low on-resistance power MOSFETs. The BD9F500QUZ DC-DC Converter offers a current of up to 5A and a fast transient response due to the Constant On-Time control system. Additionally, the Light Load Mode control improves efficiency in light-load conditions.

The ROHM BD9F500QUZ Synchronous Buck DC-DC Converter is ideal for reducing the standby power consumption of equipment. The system can control sequence via the Power Good function. The BD9F500QUZ achieves high power density and provides a small footprint on the PCB, all in a small package.
