The DIODESTM AP62500 is a 5A, synchronous buck converter with a wide input voltage range of 4.5V to 18V. The device fully integrates a 47mΩ high-side power MOSFET and an 18mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion.

The AP62500 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 AP62500 design is optimized for Electromagnetic Interference (EMI) reduction. The device has a proprietary gate driver scheme to resist switching node ringing without sacrificing MOSFET turn-on and turn-off times, which reduces high-frequency radiated EMI noise caused by MOSFET switching. The device is available in a V-QFN2030-12 (Type A) package.
