DIODES Incorporated Voltage Regulators - DC DC Switching Regulators AP63357DV-7

The AP63357DV-7 is a synchronous buck converter designed for step-down DC-DC conversion, featuring a wide input voltage range of 3.8V to 32V and a continuous output current capability of 3.5A. It integrates a high-side power MOSFET with a resistance of 74m,Ѷ and a low-side MOSFET with a resistance of 40m,Ѷ, ensuring high efficiency, with reported efficiencies up to 86% at light loads. This device operates at a switching frequency of 450kHz and includes features aimed at reducing electromagnetic interference (EMI), such as a proprietary gate driver design and Frequency Spread Spectrum (FSS) technology. The low quiescent current of 22¬µA in Pulse Frequency Modulation (PFM) mode enhances its suitability for battery-powered applications. The AP63357DV-7 is housed in a compact V-DFN3020-13 package, making it suitable for space-constrained designs. It includes protection features such as undervoltage lockout (UVLO), output undervoltage protection (UVP), cycle-by-cycle peak current limit, and thermal shutdown. This product is compliant with RoHS and is halogen and antimony-free, aligning with environmental standards. It is applicable in various fields, including consumer electronics, power tools, and distributed power supplies.
