General Description

The EC9304 is a synchronous buck controller.
The device need externals high side and external low side power MOSFETs, and provides 5A of continuous load current and a wide input voltage of 8V to 40V. 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 small TDFN-12L (3×3) package, provides a very compact solution with minimal external components.
