AP63203WU-7 – Buck Switching Regulator IC 2A SOT-23-6
The AP63203WU-7 from Diodes Incorporated is a high-efficiency 2A synchronous buck converter designed for compact, low-noise, and reliable DC/DC power conversion. With a wide input voltage range of 3.8V to 32V, it’s ideal for industrial, automotive, and consumer applications requiring stable step-down voltage regulation from various power sources. The device fully integrates a 125mΩ high-side and 68mΩ low-side power MOSFET, delivering superior efficiency and low power loss in a small SOT-23-6 (TSOT26) package.
Built on peak current mode control architecture with an integrated compensation network, the AP63203 ensures fast transient response and minimal external component requirements, simplifying design and reducing PCB space. The device incorporates advanced EMI suppression techniques, including Frequency Spread Spectrum (FSS) with ±6% frequency jitter and a proprietary gate driver scheme that minimizes switching node ringing—significantly reducing high-frequency EMI emissions. Optimized for performance, efficiency, and reliability, the AP63203 supports a switching frequency up to 2MHz, ensuring compact passive components and improved transient response. It’s an excellent choice for distributed power systems, industrial automation, communication modules, and portable electronics.
