Preliminary Datasheet

LP6492

30V 2.4A Synchronous Buck Converter

General Description

The LP6492 is a synchronous, rectified, step-down,

switch-mode converter with built-in power MOSFET.

The LP6492 offers a very compact solution that

achieves a maximum of 2.4A of continuous output

current.

The LP6492 has synchronous mode operation for high

efficiency over the output current load range.

Current-mode operation provides fast transient

response and eases loop stabilization.

The LP6492 requires a minimum number of readily

available standard external components. Other

features include cable compensation, programmable

current limit and thermal shutdown.
