AP62600 Synchronous Buck Converter Diodes Incorporated AP62600 Synchronous Buck Converter features a wide input voltage range of 4.5V to 18V and a 6A continuous output current. The AP62600 fully integrates a 36mΩ high-side power MOSFET and a 14mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion. The AP62600 device is easily used by minimizing the external component count due to its adoption of Constant On-Time (COT) control to achieve a fast transient response, easy loop stabilization, and low output voltage ripple.
