E-CMOS EC9304
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. F002 40V Synchronous Buck Controller With 2CH CC/CV EC9304 Pin Assignment The package of EC9304 is TDFN-12L (3x3) package; the pin assignment is given by: Name BS SENSE VIN GH LX GL PGND/ GND FB COMP CS1 CS2 VREF PGND PAD Description Boot-Strap Pin.GENERAL DESCRIPTION
The EC9304 is a synchronous buck controller. 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 (3x3) package, provides a very compact solution with minimal external components.FEATURES
