DIODES Incorporated Integrated Circuits (ICs) - Power Management (PMIC) - Voltage Regulators - DC DC Switching Regulators AP63356DV-7

The AP63356DV-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 of 3.5A. It integrates a 74m,Ѷ high-side and a 40m,Ѷ low-side power MOSFET, ensuring high efficiency, with reported efficiencies up to 86% at light loads. The device operates at a switching frequency of 450kHz and supports both Pulse Width Modulation (PWM) and Pulse Frequency Modulation (PFM) modes, making it suitable for various load conditions. This regulator is optimized for reduced electromagnetic interference (EMI) through a proprietary gate driver design and Frequency Spread Spectrum (FSS) technology, which helps mitigate high-frequency noise. It includes essential protection features such as undervoltage lockout (UVLO), output undervoltage protection (UVP), cycle-by-cycle peak current limit, and thermal shutdown. The AP63356DV-7 is packaged in a compact V-DFN3020-13 format, making it suitable for space-constrained applications in consumer electronics, power tools, and distributed power supplies.
