General Description

BD9B206NF-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 2 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.
