3A, 23V, Synchronous Rectified
Step-Down Converter
EC3284
General Description
Features
The EC3284 is a monolithic synchronous buck regulator.
The device integrates two 90mΩ MOSFETs, and provides
3A of continuous load current over a wide input voltage of
4.75V to 23V. Current mode control provides fast transient
response and cycle-by-cycle current limit. An adjustable
soft-start prevents inrush current at turn-on, and in shutdown
mode the supply current drops to 1µA.
This device available in an SOP8(Exposed PAD)package,
provides a very compact solution with minimal external
components.
