BD9B406NF-Z
BD9B406NF-Z is Single Synchronous Buck DC/DC Converter manufactured by ROHM.
Description
BD9B406NF-Z is one of the BD9Bx06NF-Z series of single synchronous buck DC/DC converter with built-in low on-resistance power MOSFETs. It can provide current up to 4 A. The output voltage can achieve a high accuracy due to ±1 % reference voltage. 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 6 pins 1.5 mm x 1.5 mm small package.
