NB675

24V, High Current

Synchronous Buck Converter

With +/-1.5A LDO and Buffed Reference

The Future of Analog IC Technology

DESCRIPTION

FEATURES

•

Wide 5V to 24V Operating Input Range

10A Continuous Output Current

12A Peak Output Current

The NB675 provides a complete power supply

for DDR3, DDR3L and LPDDR2 memory with

the highest power density. It integrates a high

frequency synchronous rectified step-down

switch mode converter (VDDQ) with an 1.5A

sink/source LDO (VTT) and buffered low noise

reference (VTTREF).

Built-in +/- 1.5A VTTLDO

Low R_DS(ON) Internal Power MOSFETs

Proprietary Switching Loss Reduction

Technique

•

Internal Soft Start

Output Discharge

500kHZ Switching Frequency

OCP, OVP, UVP Protection and Thermal

Shutdown

The fully integrated Buck converter is able to

deliver 10A continuous output current and 12A

peak output current over a wide input supply

range with excellent load and line regulation.

The Buck converter employs the Constant-On-

Time (COT) control scheme, which provides

fast transient response and eases loop

stabilization.

•

VDDQ Adjustable from 0.604V to 5.5V

APPLICATIONS

•

Laptop Computer

Tablet PC

The VTT LDO provides 1.5A sink/source

current capability and requires only 10uF

ceramic capacitance.

Networking Systems

Server

Personal Video Recorders

Flat Panel Television and Monitors

Distributed Power Systems

The VTTREF tracks VDDQ/2 with an excellent

1% accuracy.

Under voltage lockout is internally set as 4.5V.

An open drain power good signal indicates

VDDQ is within its nominal voltage range.

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

status, please visit MPS website under Products, Quality Assurance page.

Full protection features include OCP, OVP, and

thermal shut down.

This part requires minimum number of external

components and is available in QFN21

(3mmx4mm) package.
