General Description

The EC3284S is a monolithic synchronous buck regulator.
The device integrates 95 mΩ MOSFETS that provide 3A continuous load current over a wide operating input voltage of 4.5V to 28V.Current mode control provides fast transient response and cycle-by-cycle current limit.
An adjustable soft-start prevents inrush current at turn on.
