Overview

The AP63201WU-7 is a 2A, 500kHz synchronous buck converter designed for high-efficiency power conversion with an input voltage range of 3.8V to 32V. It features a proprietary gate driver design and Frequency Spread Spectrum (FSS) technology to significantly reduce electromagnetic interference (EMI) in sensitive systems. The device integrates high-side and low-side power MOSFETs in a compact TSOT26 package, minimizing external component count and PCB footprint.

Why Choose This Part

The component features Frequency Spread Spectrum (FSS) and a proprietary gate driver design that effectively manages EMI without requiring external shielding. It offers a low shutdown current of only 1uA and a wide input voltage range up to 32V, making it versatile for various power bus architectures. Safety features include cycle-by-cycle peak current limiting, thermal shutdown, and overvoltage protection for robust system reliability.

Applications

Getting Started

To evaluate the AP63201WU-7, designers should utilize the AP63201EVB evaluation board to test efficiency and EMI performance. When designing the PCB layout, place the input bypass capacitors as close as possible to the VIN and GND pins to minimize high-frequency noise. Refer to the datasheet's equations to select the feedback resistor divider for your target output voltage between 0.8V and 5V.
