The AP62300WU-7 is a synchronous buck converter designed for step-down DC-DC conversion with an input voltage range of 4.2V to 18V and a continuous output current of 3A. It features a low quiescent current of 155OºA and operates at a switching frequency of 750kHz, achieving up to 83% efficiency at light loads. The device integrates a 75m,Ѷ high-side and a 45m,Ѷ low-side power MOSFET, which contributes to its high efficiency and compact design by minimizing external component requirements. The AP62300WU-7 employs Constant On-Time (COT) control for fast transient response and easy loop stabilization, while its proprietary gate driver design helps reduce electromagnetic interference (EMI) during operation. It includes multiple protection features such as undervoltage lockout, cycle-by-cycle valley current limit, output undervoltage protection, and thermal shutdown. The product is available in a TSOT26 package and is fully RoHS compliant, making it suitable for various applications including consumer electronics, automotive systems, and distributed power supplies.
