NB621

8A, 25V, 600kHz Synchronous Step-Down

Converter with Integrated LDO

END OF LIFE, REFER TO NB700 OR NB693A

DESCRIPTION

FEATURES

The NB621 is a high frequency synchronous

rectified step-down switch mode converter with

a built in internal high side power MOSFET and

integrated LDO. It offers a very compact

solution to achieve 8A continuous output

current over a wide input, load and line range.

•

Wide 5.5V to 25V Operating Input Range

8A Output Current

Internal Low R_DSONPower MOSFETs

Fixed 600kHz switching frequency

Sync from 300kHz to 2MHz External Clock

Integrated 100mA LDO

Internal Compensation

Power Good Output

Integrated Bootstrap Diode

Current mode operation provides fast transient

response and eases loop stabilization.

Full protection features include OCP and thermal

shut down.

OCP Protection and Thermal Shutdown

Output Adjustable from 0.8V to 15V

Available in 4mm x 5mm 28-pin QFN package.

The NB621 requires a minimum number of

readily available standard external components

and is available in a space saving 4mm x 5mm

28-pin QFN package.

APPLICATIONS

•

Notebook Systems and I/O Power

Networking Systems

Digital Set Top Boxes

Personal Video Recorders

Flat Panel Television and Monitors

Distributed Power Systems
