Description

The AP61062Q is an automotive-compliant, 600mA, 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 a 80mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion.

The AP61062Q 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 the SOT563 package.
