NB649

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

Converter with Integrated LDO

END OF LIFE, REFER TO NB700 OR NB693A

DESCRIPTION

FEATURES

The NB649 is a high frequency synchronous

rectified step-down switch mode converter with

a built in LDO regulator. 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_DS(ON) Power MOSFETs

Fixed 600kHz switching frequency

Sync from 300kHz to 1MHz External Clock

Integrated 100mA LDO

Internal Compensation

Power Good Output

Integrated Bootstrap Diode

Full protection features include OCP and thermal

shut down.

The NB649 requires a minimum number of

readily available standard external components

and is available in a space saving 5mm x 6mm

30-pin QFN package.

OCP Protection and Thermal Shutdown

Output Adjustable from 0.8V to 15V

Available in 5mm x 6mm 30-pin QFN package.
