AP64060

Description

The AP64060/AP64062 are a 600mA, synchronous buck converter with a wide input voltage range of 4.5V to 40V. The device fully integrates a 600mΩ high-side power MOSFET and a 300mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion.

The AP64060/AP64062 devices are easily used by minimizing the external component count due to its adoption of peak current mode control along with its integrated loop compensation network.

The AP64060/AP64062 designs are 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 devices are available in the TSOT26 package.
