NB632

High Effeciency 4A, 24V, 500kHz

Synchronous Step-down Converter

END OF LIFE, REFER TO NB691A OR NB692

DESCRIPTION

FEATURES

The NB632 is a high frequency synchronous

rectified step-down switch mode converter with

built-in internal power MOSFETs. It offers a

very compact solution to achieve 4A continuous

output current over a wide input supply range

with excellent load and line regulation. The

NB632 operates at high efficiency over a wide

output current load range.

•

Wide 4.5V to 24V Operating Input Range

4A Output Current

Low R_DS(ON) Internal Power MOSFETs

Proprietary Switching Loss Reduction

Technique

Fixed 500kHz Switching Frequency

Sync from 300kHz to 2MHz External Clock

Internal Compensation

Latch-off OCP Protection and Thermal

Shutdown

•

Current mode operation provides fast transient

response and eases loop stabilization.

•

Output Adjustable from 0.8V

Available in a 14-pin, QFN 3x4mm Package

Full protection features include latch-off OCP and

thermal shut down.

APPLICATIONS

The NB632 requires a minimum number of

readily available standard external components

and is available in a space saving 3mm x 4mm

14-pin QFN package.
