General Description<\/h3>\n\n\n\n

The EC9303 is a monolithic synchronous buck regulator.
The device integrates internal high side and external low side power MOSFETs, and provides 5A of continuous load current over a wide input voltage of 8V to 38V.
Current mode control provides fast transient response and cycle-by-cycle current limit.
An internal soft-start prevents inrush current at turn-on, This device available in SOP8L-EP (Exposed pad) package, provides a very compact solution with minimal external components.<\/p>\n\n\n\n
