The AP62300/AP62301/AP62300T is a 3A, synchronous buck converter with a wide input voltage range of 4.2V to 18V. The device fully integrates a 75mΩ high-side power MOSFET and a 45mΩ lowside power MOSFET to provide high-efficiency step-down DC-DC conversion.
The AP62300/AP62301/AP62300T 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 AP62300/AP62301/AP62300T 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 highfrequency radiated EMI noise caused by MOSFET switching.
AP62300/AP62301 is available in a SOT563 and TSOT26 package. AP62300T is available in a TSOT26 package.
