24V, High Current

Synchronous Step-down Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The NB671 is a fully integrated high frequency

synchronous rectified step-down switch mode

converter. It offers very compact solutions to

achieve 6A continuous output current and 9A

peak current over a wide input supply range

with excellent load and line regulation. The

NB671 operates at high efficiency over a wide

output current load range.

•

Wide 5V to 24V Operating Input Range

6A Continuous Output Current

9A Peak Output Current

Low R_DS(ON) Internal Power MOSFETs

Proprietary Switching Loss Reduction

Technique

1% Reference Voltage

1.7ms Internal Soft Start

Output Discharge

•

Constant-On-Time

(COT)

control

mode

provides fast transient response and eases loop

stabilization.

500kHZ Switching Frequency

OCP, OVP, UVP Protection and Thermal

Shutdown

Under voltage lockout is internally set as 4.6V,

An open drain power good signal indicates the

output is within its nominal voltage range.

•

Output Adjustable from 0.604V to 5.5V

APPLICATIONS

Full protection features include OCP, OVP, and

thermal shut down.

•

Laptop Computer

Tablet PC

Networking Systems

Personal Video Recorders

Flat Panel Television and Monitors

Distributed Power Systems

The converter requires minimum number of

external components and is available in QFN16

(3mmx3mm) package.

All MPS parts are lead-free and adhere to the RoHS directive. For MPS green
