The 7Semi DC Buck Converter Breakout with 3.3V 2A Output is a precision-engineered power module designed to deliver a stable and efficient step-down voltage conversion. Leveraging the robust AP62301 synchronous buck converter, this breakout board operates across a wide input voltage range of 4.2V to 14V, producing a fixed 3.3V output at up to 2A. It is specifically crafted to address and reduce Electromagnetic Interference (EMI) with a proprietary gate driver scheme that minimises switching node ringing—without sacrificing MOSFET performance - ensuring reliable operation in noise-sensitive environments.

Compact in size yet powerful in functionality, this module integrates seamlessly into modern electronics, from embedded systems and IoT devices to portable battery-powered applications. The advanced synchronous buck topology ensures low output ripple, high efficiency, and stable regulation under varying loads. Built-in safety features like over-temperature protection, over-current protection, and a soft-start mechanism safeguard your circuits while extending the life of your electronic components.
