EC3284S – 3A 28V Synchronous Buck Converter

General description

The EC3284S is a monolithic synchronous buck regulator. The device integrates 95 mΩ MOSFETS that provide3Acontinuous load current over awideoperatinginputvoltage of4.5Vto 28V.Current mode control provides fast transient responseandcycle-by-cyclecurrentlimit. An adjustable soft-start prevents inrush current at turn on.
