3A 32V Synchronous Rectified Step-Down
Converter
EC3286
General Description
Features
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
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.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.
