DIODES Incorporated Voltage Regulators - DC DC Switching Regulators AP63356QZV-7

The AP63356QZV-7 is an automotive-compliant synchronous buck converter designed for efficient step-down DC-DC conversion. It operates within a wide input voltage range of 3.8V to 32V and can deliver a continuous output current of 3.5A. The device features integrated high-side and low-side power MOSFETs with on-resistances of 74mOc and 40mOc, respectively, contributing to high efficiency, which can reach up to 86% at light loads. This regulator employs peak current mode control and includes an integrated loop compensation network, simplifying the design and minimizing external component requirements. It is optimized for reduced electromagnetic interference (EMI) through a proprietary gate driver design and frequency spread spectrum technology, which helps mitigate high-frequency noise. The AP63356QZV-7 is packaged in a compact 3mm x 2mm V-DFN3020-13/SWP package, making it suitable for space-constrained applications. It is AEC-Q100 qualified, ensuring reliability in automotive environments, and includes various protection features such as undervoltage lockout, output undervoltage protection, and thermal shutdown. This device is ideal for automotive power systems, infotainment, instrument clusters, body electronics, telematics, and advanced driver assistance systems.
