Dear all,

                I need an ref device and ref Design circuit for my following design specfications of BUCK converter (30VDC to 13.5VDC 14A). Please refer the suitable SWITCH for my applications and refer circuit design example if any. Source is Solar panel can deliver 30V 240W and output use for battery charging.





our hiper family will deal with the applications with a few hundreds watts of output power.  Right now our design reference is with AC input if it is a PFC+LLC system. Or with single  LLC stage, the deisgn example is with high Vdc input, ~380Vdc. 

You can use our parameter seach website to get better understanding of availible design references.
