AP63356DV-7

The AP63356DV-7 from Diodes Incorporated is a high-efficiency synchronous buck converter capable of delivering up to 3.5A of continuous output current. It operates over a wide input voltage range from 3.8V to 32V, making it suitable for various power bus applications.

This device integrates a 74mΩ high-side and a 40mΩ low-side power MOSFET. It features peak current mode control and an integrated loop compensation network, minimizing external component count. The design is optimized for Electromagnetic Interference (EMI) reduction through a proprietary gate driver scheme and Frequency Spread Spectrum (FSS) technology.

The AP63356DV-7 is available in a compact 3mm x 2mm V-DFN3020-13 package, suitable for surface mounting. Key electrical specifications include a 450kHz switching frequency and a low quiescent current of 22µA in Pulse Frequency Modulation mode. It also offers features like a Power Good indicator and precision enable threshold for UVLO adjustment.

Applications for this converter include 5V, 12V, and 24V distributed power bus supplies, flat-screen TV sets, monitors, power tools, laser printers, white goods, small home appliances, FPGA, DSP, ASIC supplies, home audio, network systems, gaming consoles, and general-purpose point-of-load applications.
