描述
BD9B306NF-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 3A. 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 1.5mm x 1.5mm small package.

2.7 V to 5.5 V Input, 3.0 A Integrated MOSFET

Single Synchronous Buck DC/DC Converter

BD9B306NF-Z

General Description

Key Specifications

BD9B306NF-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 3 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.
