EC3293-3A,18V,Syn. Step-down DC/DC Converter

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 excellentload 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 andthermal 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.
