The ACP2827 and ACP2827B is a 1A, synchronous buck
converter with a wide input voltage range of 2.3V to 5.5V.
The device fully integrates a 110mΩ high-side power
MOSFET and an 80mΩ low-side power MOSFET to
provide high-efficiency step-down DC-DC conversion.
The ACP2827 and ACP2827B device is easily used by
minimizing the external component count due to its
adoption of Constant On-Time (COT) control to achieve
fast transient response, easy loop stabilization, and low
output voltage ripple.
The device is available in a SOT563 package.
