General Description
The EC3276 is a monolithic synchronous buck regulator.
The device integrates two 90mΩ MOSFETs, and provides 2.2A of continuous load current over a wide input voltage of 4.75V to 32V.
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 SOP-8(Exposed PAD)package, provides a very compact solution with minimal external components.
