The 7SEMI AP64350 Buck Converter Board delivers a stable 5V regulated output at up to 1.5A from wide-range input voltages between 3.8V and 40V. Built around the AP64350SP-13, a high-efficiency synchronous buck converter by Diodes Inc., this compact board is ideal for powering MCUs, sensors, communication modules, or any 5V logic device.
With low quiescent current, EMI-optimized design, and integrated protections, it’s a reliable and space-efficient option for DIY electronics, automation systems, IoT nodes, or industrial tools.
