AP63357DV-7 Description

Short technical summary and product information.

The Diodes Incorporated AP63357DV-7 is a high-efficiency synchronous buck converter designed for step-down DC-DC conversion. It supports a wide input voltage range from 3.8V to 32V and can deliver up to 3.5A of continuous output current.

 

This device integrates a 74mΩ high-side and a 40mΩ low-side power MOSFET. It utilizes peak current mode control with an integrated loop compensation network, minimizing external component count. The AP63357DV-7 is optimized for Electromagnetic Interference (EMI) reduction through a proprietary gate driver scheme and Frequency Spread Spectrum (FSS) technology, which jitters the switching frequency by ±6% to reduce radiated noise.

 

Key features include a low quiescent current of 22µA in Pulse Frequency Modulation mode, a typical switching frequency of 450kHz, and up to 86% efficiency at light loads. It also offers protection features such as Undervoltage Lockout (UVLO), Output Undervoltage Protection (UVP), Cycle-by-Cycle Peak Current Limit, and Thermal Shutdown.

 

The AP63357DV-7 is available in a compact 3mm x 2mm V-DFN3020-13 package, suitable for surface mounting. Its applications include distributed power bus supplies, consumer electronics, and FPGA/DSP/ASIC power supplies.
