EC3293A-3A, 18V, 500KHz, Syn. DC/DC Converter

 General description

The  EC3293A  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 EC3293A  has  synchronous-mode operation for higher  efficiency over the output current-load range.

Current-mode  operation provide fast transient

response and eases loop stabilization.

Protection features include over-current protection and

thermal shutdown. The  EC3293A  requires  a  minimal  number  of  readily

available, standard external components and is available

in a space-saving TSOT23-6L package.
