Description

The AP62150 is a 1.5A, synchronous buck converter with a wide input voltage range of 4.2V to 18V. The device fully integrates a 90mΩ highside power MOSFET and a 65mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion.

The AP62150 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 AP62150 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.

AP62150 is available in SOT563 and TSOT26 packages.
