General Description

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.
