AP62250 Synchronous Buck Converters Diodes Incorporated AP62250 Synchronous Buck Converters are 2.5A power converters that operate at 4.2V to 18V input voltage range. These converters feature a 75mΩ high-side power MOSFET and a 45mΩ low-side power MOSFET that provides high-efficiency step-down DC-DC conversion. The AP62250 converters offer Constant On-Time (COT) control to achieve a fast transient response, easy loop stabilization, and low output voltage ripple. These converters are optimized for Electromagnetic Interference (EMI) reduction and are available in SOT563 and TSOT26 packages.
