The AP61100Q/AP61102Q is an automotive-compliant, 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 AP61100Q/AP61102Q 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.
