General Description

The EC3286 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 32V.

Current mode control provides fast transient response and cycleby-cycle current limit. An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to 1µA.

The EC3286 regulates the output voltage in automatic PSM/PWM mode operation, depending on the output current, for high efficiency operation over light to full load current. This device, available in an SOP-8(Exposed PAD) package, provides a very compact solution with minimal external components.
