EC3293

3A, 18V, Synchronous Step-down DC/DC Converter

General Description

Features

The EC3293 is a high-frequency, synchronous, rectified,

step-down, switch-mode converter with internal power

MOSFETs. It offers a very compact solution to achieve

a 3A continuous output current over a wide input supply

range, with excellent load and line regulation.

The EC3293 has synchronous-mode operation for higher

efficiency over the output current-load range.

Current-mode operation provides fast transient response

and eases loop stabilization.

Protection features include over-current protection and

thermal shutdown.

The EC3293 requires a minimal number of readily

available, standard external components and is available

in a space-saving SOP-8L(Exposed Pad) package.
